MAXIM MAX148/MAX149 +2.7V to +5.25V Low-Power 8-Channel Serial 10-Bit ADCs handbook
The MAX148 and MAX149 are 10‑bit, 8‑channel analog‑to‑digital converters that operate from a single supply of +2.7 V to +5.25 V. They feature a low‑power consumption of about 1.2 mA at 133 ksps (3 V supply) and provide both unipolar/bipolar and single‑ended/differential input configurations. The devices include an internal 2.5 V reference (MAX149) or an external reference option (MAX148) and support a 4‑wire serial interface compatible with many microprocessors.
The datasheet includes absolute maximum ratings, electrical characteristics, timing specifications, pin descriptions, and package dimensions for the 20‑pin DIP and SSOP versions. Detailed sections cover digital input/output voltage levels, shutdown behavior, conversion rate, and typical operating characteristics such as SINAD, THD, and SFDR.
