The MAX1978/MAX1979 are the smallest, safest, most accurate complete single-chip temperature controllers for Peltier thermoelectric cooler (TEC) modules.

The MAX9217 is a digital video parallel-to-serial converter. It serializes 27 bits of parallel data into a serial data stream. Eighteen bits of video data and 9 bits of control data are encoded and multiplexed onto the serial interface, reducing the serial data rate. The MAX9217 pairs with the MAX9218 deserializer to form a complete digital video serial link. Interconnect can be controlled-impedance PCB traces or twisted-pair cable. Proprietary data encoding reduces EMI and pro- vides DC balance. DC balance allows AC-coupling, providing isolation between the transmitting and receiv- ing ends of the interface. The LVDS output is internally terminated with 100Ω. ESD tolerance is specified for ISO 10605 with ±10kV contact discharge and ±30kV air discharge. The MAX9217 operates from a +3.3V core supply and features a separate input supply for interfacing to 1.8V to 3.3V logic levels. This device is available in 48-lead Thin QFN and LQFP packages and is specified from -40°C to +85°C.

The MAX6950/MAX6951 are compact common-cathode display drivers that interface microprocessors to individual 7-segment numeric LED digits, bar graph, or discrete LEDs through an SPI™-, QSPI™-, MICROWIRE™-compatible serial interface.

The MAX1181 is a 3V, dual 10-bit, analog-to-digital converter (ADC) featuring fully-differential wideband track-and-hold (T/H) inputs, driving two pipelined, nine- stage ADCs. The MAX1181 is optimized for low-power, high-dynamic performance applications in imaging, instrumentation, and digital communication applications. The MAX1181 operates from a single 2.7V to 3.6V supply, consuming only 246mW, while delivering a typi- cal signal-to-noise ratio (SNR) of 59dB at an input fre- quency of 20MHz and a sampling rate of 80Msps. The T/H driven input stages incorporate 400MHz (-3dB) input amplifiers. The converters may also be operated with single-ended inputs. In addition to low operating power, the MAX1181 features a 2.8mA sleep mode, as well as a 1µA power-down mode to conserve power during idle periods. An internal 2.048V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of the internal or external reference, if desired for applications requiring increased accuracy or a different input voltage range. The MAX1181 features parallel, CMOS-compatible three-state outputs. The digital output format is set to two’s complement or straight offset binary through a single control pin. The device provides for a separate output power supply of 1.7V to 3.6V for flexible interfac- ing. The MAX1181 is available in a 7mm ✕ 7mm, 48-pin TQFP package, and is specified for the extended industrial (-40°C to +85°C) te

The MAX1693/(MAX1693H)/MAX1694 are current-limited, 60mΩ switches with built-in fault blanking. Their accurate preset current limit of 0.7A to 1.0A makes them ideally suited for USB applications. Their low quiescent supply current (14µA) and shutdown current (1µA) con- serve battery power in portable applications. The MAX1693/(MAX1693H)/MAX1694 operate with inputs from 2.7V to 5.5V, making them ideal for both 3V and 5V systems. A fault signal notifies the microprocessor that the inter- nal current limit has been reached. A 10ms fault-blank- ing feature allows momentary faults (such as those caused when hot-swapping into a capacitive load) to be ignored, thus preventing false alarms to the host system. This fault blanking also prevents a fault signal from being issued when the device is powering up. In the MAX1693/(MAX1693H), an output overcurrent condition causes the switch to current limit at 0.7A to 1.0A and FAULT to go low after the 10ms blanking peri- od. When the overcurrent condition is removed, FAULT returns to its high-impedance state. In the MAX1694, any overcurrent longer than 10ms will latch the switch open and set FAULT low. The latch is cleared by cycling the ON input or by powering up the device again. This feature saves power by preventing the device from ther- mal cycling on and off in case of a persistent short-cir- cuit condition. The MAX1693/(MAX1693H)/MAX1694 have several safety features to ensure that the USB port is protected.

The MAX8645X/MAX8645Y is an LED power management chip for camera modules, which can drive up to 8 white LEDs with high efficiency and low EMI.

MAX6977 is one of the MAX697x series. The MAX697x series is an 8-channel LED driver that uses an industry standard 4-wire serial interface and supports PWM control.

This datasheet provides detailed information on the operation and features of the MAX6877/MAX6878/MAX6879 multivoltage power trackers/sequencers/supervisors, including voltage tracking, power sequencing, fault detection and recovery.

The MAX709 is an integrated circuit used in +5V, +3.3V, and +3V powered systems to provide system reset during power-up, power-down, and brownout conditions.

The MAX5128 is a nonvolatile, single-channel, linear-taper digital potentiometer with 128 taps and 22kΩ end-to-end resistance. It replaces the function of a mechanical potentiometer with a simple 2-wire digital interface. The MAX5128 features an ultra-small 2mm x 2mm µDFN package and a low standby supply current of 0.5µA (typical), making it ideal for portable applications. The digital potentiometer can recall the programmed wiper position from nonvolatile memory and can be programmed using a simple 2-wire up/down interface. It provides a low temperature coefficient of 5ppm/°C and is specified over the extended -40°C to +85°C temperature range.

The MAX1444 is a 10-bit, 3V analog-to-digital converter (ADC) that features a pipelined 10-stage ADC architecture with fully differential wideband track-and-hold (T/H) input and digital error correction incorporating a fully differential signal path. This ADC is optimized for low- power, high dynamic performance applications in imaging and digital communications.

The MAX6956 is a multi-function LED display driver/I/O expander from Texas Instruments that has 28 ports that can be individually configured as logic inputs, logic outputs, or common-anode (CA) LED constant-current segment drivers.
