MAX144BCUA+

The MAX144BCUA+ is a 2.7V, low power, 2-channel, 108Ksps, serial 12bit ADC in 8 pin µMAX package. The device operates 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. 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 makes this device ideal for battery powered and data acquisition applications.
