Product details

16-bit sigma-delta ADC with internal oscillator and temperature sensor

The MCP3464RT-E/ST is a 16-bit sigma-delta ADC from Microchip, sampling at 153.6 ksps. It integrates an internal oscillator and a temperature sensor, so you get a self-contained conversion chain without external clock or thermistor — the temperature sensor output can be read through the same SPI interface, useful for compensating drift in the measurement path.

Input configuration and supply rails

Four input channels, configurable as differential or single-ended, feed a MUX-ADC front end — no external mux needed for multi-sensor scanning.

Frequently asked questions

What is the closest functional alternative to MCP3464RT-E/ST?

The MCP3564T-E/NC is a 24-bit variant in the same sigma-delta family, also with SPI interface and internal oscillator/temperature sensor, but it adds a PGA and supports up to 8 input channels. The MCP3464RT-E/ST is 16-bit with 4 channels and no PGA — the choice depends on whether you need the extra resolution and gain or the simpler, lower-power front end.

What compliance documentation does Microchip provide for MCP3464RT-E/ST?

The part is RoHS3 compliant per Microchip's lifecycle record. Standard documentation includes the datasheet, application notes, and a RoHS certificate of compliance — available on request.
