Power consumption is only 5.7mW (VDD = VLOGIC) at the maximum sampling rate of 250ksps. Two software-selectable power-down modes enable the MAX1061/MAX1063 to be shut down between conversions; accessing the parallel interface returns them to normal operation. Powering down between conversions can cut supply current to under 10µA at reduced sampling rates. Both devices offer software-configurable analog inputs for unipolar/bipolar and single-ended/pseudo-differential operation. In single-ended mode, the MAX1061 has eight input channels and the MAX1063 has four input channels (four and two input channels, respectively, when in pseudo-differential mode).

The MAX1040-MAX1049 is an integrated multichannel 10-bit analog-to-digital converter (ADC) and a quad, 10-bit digital-to-analog converter (DAC) in a single IC. The device also includes a temperature sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial interface. The ADC is available in a 4 or an 8 input-channel version. The four DAC outputs settle within 2.0µs, and the ADC has a 300ksps conversion rate. All devices include an internal reference (2.5V or 4.096V) providing a well-regulated, low-noise reference for both the ADC and DAC. Programmable reference modes for the ADC and DAC allow the use of an internal reference, an external reference, or a combination of both. Features such as an internal ±1°C accurate temperature sensor, FIFO, scan modes, programmable internal or external clock modes, data averaging, and AutoShutdown™ allow users to minimize both power consumption and processor requirements. The low glitch energy (4nV•s) and low digital feedthrough (0.5nV•s) of the integrated quad DACs make these devices ideal for digital control of fast- response closed-loop systems. The devices are guaranteed to operate with a supply volt- age from +2.7V to +3.6V (MAX1041/MAX1043/MAX1047/ MAX1049) and from +4.75V to +5.25V (MAX1040/ MAX1042/MAX1046/MAX1048). These devices consume 2.5mA at 300ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode.

The MAX1044 and ICL7660 are monolithic, CMOS switched-capacitor voltage converters that invert, double, divide, or multiply a positive input voltage. They are pin compatible with the industry-standard ICL7660 and LTC1044. Operation is guaranteed from 1.5V to 10V with no external diode over the full temperature range. They deliver 10mA with a 0.5V output drop. The MAX1044 has a BOOST pin that raises the oscillator frequency above the audio band and reduces external capacitor size requirements. The MAX1044/ICL7660 combine low quiescent current and high efficiency. Oscillator control circuitry and four power MOSFET switches are included on-chip. Applications include generating a -5V supply from a +5V logic supply to power analog circuitry. For applications requiring more power, the MAX660 delivers up to 100mA with a voltage drop of less than 0.65V.

The MAX104 is a PECL-compatible, 1Gsps, 8-bit analog-to-digital converter (ADC) that allows accurate digitizing of analog signals with bandwidths up to 2.2GHz. It is fabricated on Maxim's proprietary advanced GST-2 bipolar process, integrating a high-performance track/hold (T/H) amplifier and a quantizer on a single monolithic die. The innovative design of the internal T/H, which has an exceptionally wide 2.2GHz full-power input bandwidth, results in high performance (greater than 7.5 effective bits) at the Nyquist frequency. A fully differential comparator design and decoding circuitry reduce out-of-sequence code errors (thermometer bubbles or sparkle codes) and provide excellent metastable performance of one error per 1016 clock cycles. Unlike other ADCs that can have errors resulting in false full- or zero-scale outputs, the MAX104 limits the error magnitude to 1LSB. The analog input is designed for either differential or single-ended use with a ±250mV input voltage range. Dual, differential, PECL-compatible output data paths ensure easy interfacing and include an 8:16 demultiplexer feature that reduces output data rates to one-half the sampling clock rate. The PECL outputs can be operated from any supply between +3V to +5V for compatibility with +3.3V or +5V referenced systems. Control inputs are provided for interleaving additional MAX10
