This document introduces the features and characteristics of Microchip Technology Inc. MCP3302/04 13-bit A/D converters, including full differential inputs, single/differential inputs, ±1 LSB maximum DNL, ±1 LSB maximum INL, single supply operation, 100 ksps sampling rate, 50 nA typical standby current, 450 µA maximum operating current, industrial temperature range, etc.
The MCP3302/04 family are 13‑bit successive‑approximation A/D converters with full differential inputs and low power consumption, suitable for battery‑operated and remote‑sensor applications. The MCP3302 provides two differential or four single‑ended inputs, while the MCP3304 offers four differential or eight single‑ended inputs.
Key features include a sampling rate up to 100 ksps at 5 V, operating voltage range 2.7 V–5.5 V, standby current as low as 50 nA, and operation over an industrial temperature range of –40 °C to +85 °C. The devices are offered in 14‑pin PDIP, 16‑pin PDIP, 150‑mil SOIC and TSSOP packages.
