The MAX1117/MAX1118/MAX1119 are low-power, 8-bit, dual-channel analog-to-digital converters (ADCs) with internal track/hold (T/H) voltage reference, clock, and serial interface. They feature low power consumption, automatic shutdown mode, and internal clock, making them suitable for various applications.
The MAX1117, MAX1118, and MAX1119 are single‑supply, low‑power, dual‑channel analog‑to‑digital converters with an 8‑bit resolution. They operate from 2.7 V to 5.5 V depending on the part and include an internal reference, track‑hold circuitry, and a 3‑wire serial interface compatible with SPI, QSPI, and MICROWIRE.
Key features include ultra‑low supply current (as low as <1 µA in shutdown), conversion rates up to 100 ksps, and a small 8‑pin SOT‑23 package. Typical applications are handheld devices, battery‑powered test equipment, and remote data‑acquisition systems.
