Analog Devices introduces integrated AD4880 for scientific instruments

Analog Devices Inc. (ADI) has introduced the AD4880, a dual-channel, 20-bit successive approximation register (SAR) analog-to-digital converter (ADC) designed as an integrated analog front end (AFE).

To address challenges in developing next-generation scientific instruments—such as flow cytometry, spectroscopy, and digital imaging—the AD4880 integrates several precision components. These include fully differential amplifiers, gain-setting resistors, low-drift reference buffers, LDO regulators, and critical decoupling capacitors. This integration aims to simplify the design process for engineers facing constraints in channel density, acquisition speed, and precision.

The device supports input signals up to 1MHz and features built-in digital capabilities such as oversampling, digital filtering, and decimation. It also includes dual multilane LVDS interfaces for low-latency data transfer and an integrated FIFO to support asynchronous SPI access, which can reduce processor loading.
