ADC32RF42IRMP

Analog To Digital Converters (ADC) Overview

The ADC32RF42IRMP is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports a maximum sampling rate of 1.5 GSPS and accepts RF input frequencies up to 4 GHz. The device features an integrated digital downconverter (DDC) with up to four channels per ADC and three independent numerically controlled oscillators (NCOs). Key performance metrics include a noise spectral density of -151.8 dBFS/Hz, aperture jitter of 90 fS, and channel isolation of 95 dB at 1.8 GHz. It utilizes a JESD204B interface with deterministic latency based on subclass 1, supporting data rates up to 12.5 Gbps per lane. The component operates within an industrial temperature range of -40°C to +85°C.
