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 V REF . An external clock accesses datathrough the 3-wire serial interface, which is SPITM, QSPITM, and MICROWIRETM-compatible. Excellent dynamic performance and low power, combined with ease of use and small package size, make these converters ideal for battery-powered and dataacquisition applications, or for other circuits with demanding power-consumption and space requirements. For pin-compatible 10-bit ADCs, see the MAX157 and MAX159.
