Overview

  • Single-Supply Operation (+2.7V to +5.25V)
  • Two Single-Ended Channels (MAX144) One Pseudo-Differential Channel (MAX145)
  • Low Power
    • 0.9mA (108ksps, +3V Supply)
    • 100µA (10ksps, +3V Supply)
    • 10µA (1ksps, +3V Supply)
    • 0.2µA (Power-Down Mode)
  • Internal Track/Hold
  • 108ksps Sampling Rate
  • SPI/QSPI/MICROWIRE-Compatible 3-Wire Serial Interface
  • Space-Saving 8-Pin µMAX Package
  • Pin-Compatible 10-Bit Versions Available

The MAX144/MAX145 low-power, 12-bit analog-to-digital converters (ADCs) are available in 8-pin µMAX® and DIP packages. Both devices operate with a single +2.7V to +5.25V supply and feature a 7.4µs successive- approximation ADC, automatic power-down, fast wake-up (2.5µs), an on-chip clock, and a high-speed, 3-wire serial interface.

Power consumption is only 3.2mW (VDD = +3.6V) at the maximum sampling rate of 108ksps. At slower throughput rates, the automatic shutdown (0.2µA) further reduces power consumption.

The MAX144 provides 2-channel, single-ended operation and accepts input signals from 0 to VREF. The MAX145 accepts pseudo-differential inputs ranging from 0 to VREF. An external clock accesses data-through the 3-wire serial interface, which is SPI™, QSPI™, and MICROWIRE™-compatible.

Excellent dynamic performance and low power, combined with ease of use and small package size, make these converters ideal for battery-powered and data-acquisition applications, or for other circuits with demanding power-consumption and space requirements. For pin-compatible 10-bit ADCs, see the MAX157 and MAX159 data sheets.
