Overview
The ADC32RF83IRMPT is a dual-channel, 14-bit, 3-GSPS (gigasamples per second) RF sampling wideband receiver and feedback IC produced by Texas Instruments. This device is part of the ADC32RF8x family, which is designed for high signal-to-noise ratio (SNR) and dynamic range, making it suitable for various high-frequency applications. The ADC32RF83IRMPT supports RF input frequencies up to 4 GHz and beyond, with a noise spectral density of –155 dBFS/Hz. It features on-chip digital down-converters (DDCs) and multiple independent numerically-controlled oscillators (NCOs) for phase-coherent frequency hopping. The device is packaged in a 72-pin VQFN (Very Thin Quad Flat No-Lead) package with an exposed pad, ensuring efficient thermal management and compact design.
