Maxim MAX148/MAX149 Datasheet
The MAX148 and MAX149 are 10‑bit, low‑power, 8‑channel (or 4‑channel) data‑acquisition ADCs with a single‑supply operation from +2.7 V to +5.25 V. They feature an on‑chip multiplexer, track/hold circuitry, and a 4‑wire serial interface compatible with TMS320 DSPs.
The devices offer internal (MAX149) or external reference options, selectable unipolar/bipolar inputs, and a maximum conversion rate of 133 ksps. Detailed pin functions, timing diagrams, and package dimensions are provided for DIP and SSOP formats.
