AD1974 Datasheet (Analog Devices)

AD1974, ADC

The AD1974 is a high performance, single-chip codec that provides four analog-to-digital converters (ADCs) with differential inputs using the Analog Devices, Inc.

patented multibit sigmadelta (Σ-Δ) architecture.

An SPI port is included, allowing a microcontroller to adjust volume and many other para
