AD1988BJCPZ-RL

Overview

The AD1988BJCPZ-RL is a High Definition Audio SoundMAX codec manufactured by Analog Devices Inc. It integrates four analog-to-digital converters and eight digital-to-analog converters with a built-in programmable phase-locked loop. The device supports sampling rates up to 192 kHz and offers 24-bit resolution for both ADC and DAC channels. It operates within a supply voltage range of 3.0 V to 3.6 V and functions reliably across an industrial temperature range from -40°C to +85°C. The component utilizes a serial interface for data communication and is housed in a 48-pin LQFP package.
