The LTC2656 is a 16-bit, eight-channel voltage output DAC from Linear Technology. It features guaranteed ±4LSB INL and ±1LSB DNL, and achieves ultralow AC and DC crosstalk to ensure rock-solid control in precision multichannel open or closed loop systems. The complete family of quad and octal DACs integrates a precision 1.25V or 2.048V reference that achieves 2ppm/°C typical and 10ppm/°C maximum temperature coefficient. The ±4LSB (max) INL, ±2mV (max) offset error and ±0.1% (max) gain error DC specifications ensure you’re designing with the industry’s best unipolar DACs.

RS232 is a standard for conveying data over a simple unterminated, multiconductor cable at rates up to 20kB. It specifies the electrical characteristics and connector for an all encompassing point-to-point modem interface. The standard has been expanded for use as a general purpose serial interface at data rates up to 1MB.

They provide a wide input voltage range (4V to 80V), adjustable output clamp voltage, reverse input protection to -60V, adjustable fault timer, overcurrent protection, inrush limiting, auxiliary amplifier and -40°C to 125°C operation.

This document introduces a series of high-precision high-side current sense amplifier products from Linear Technology Corporation, including LT1999, LTC6102, LTC6102HV, etc. These products feature high accuracy, high-speed response, and low power consumption, which can be used to measure load currents ranging from microamps to amps.

The LTC6655 is a linear voltage reference from Linear Technology with outstanding noise performance, low temperature drift, and wide supply range. It is an ideal choice for demanding automotive, industrial, and instrumentation applications.

This document introduces the LTC2941/LTC2942 coulomb counters, which are used for accurate lithium battery gauging. The counters use continuous-time analog integrators, resulting in minimal offset and gain errors, and better overall charge accuracy. The bidirectional analog integrator accommodates both battery charge and discharge, and a programmable prescaler allows for a wide range of battery capacities. The LTC2942 also incorporates a 14-bit ∆∑ ADC to measure battery voltage and die temperature. The LTC2941-1 and LTC2942-1 also integrate a 50mΩ sense resistor to provide up to ±1A measurement range. Charge, voltage* and temperature* are all communicated to the host system over an I2C/SMBus compatible interface.

This document describes a MOSFET circuit with a small footprint and low resistance. It has a wide operating voltage range and features adjustable current limit, temperature monitoring, overtemperature protection, and overcurrent protection.

The LTC2383-16 is a 1Msps, no latency SAR ADC that offers low 13mW power consumption, 92dB SNR using a fully differential input range, ±2LSB INL (max) and 16-bit no missing codes resolution. The pin- and software-compatible family includes LTC2382-16 (500ksps) and LTC2381-16 (250ksps) and features a proprietary sampling architecture that allows the use of extremely low power ADC drivers, thus reducing the overall power consumption of the entire data acquisition solution. To achieve uncompromised AC performance, we recommend the fast settling LT®6350 ADC driver for single-ended to differential conversion of input signals. We also recommend the LTC6652-2.5, a precision external reference with high accuracy, low power and small size. The –40°C to 125°C temperature range of LT6350 and LTC6652 complements that of LTC2383 family and makes them ideal for automotive applications.

LTC2351/2356 family of SAR ADCs are low-power, low-cost, high-performance ADCs.

The document is about LTC3675 power management chip. The chip is a highly integrated general-purpose power management solution for high power single cell lithium-ion/polymer systems. It features seven independent rails plus LED driver, with I2C control, flexible sequencing and fault monitoring in a compact 28mm2 QFN package.

The LTC2990 is a temperature, voltage and current monitor for 3V to 5.5V systems which integrates a 14-bit ADC, 10ppm/°C reference and I2C interface to provide submillivolt voltage resolution, as well as accuracy of ±1°C internally and ±0.5°C remotely when making temperature measurements. Unlike traditional temperature monitors that rely on single-ended inputs for measurements, the LTC2990 uses four differential inputs to measure multiple parameters simultaneously.

The LT3748 is a high input voltage isolated flyback DC/DC controller that does not require an opto-isolator, third winding or signal transformer for feedback. The output voltage is sensed from the primary-side flyback signal, and is set with two external resistors and the transformer turns ratio. The LT3748 operates over a 5V to 100V input voltage range, drives an external N-channel power MOSFET and maintains better than ±5% overall regulation.
