概述

Description

ADS4142IRGZR is a Texas Instruments high-speed, high-resolution analog-to-digital converter (ADC). It provides 16-bit digital conversion of a wideband analog input at very high sampling rates, suitable for radar, communications, instrumentation, and test equipment. The device combines differential analog inputs, strong dynamic performance (low distortion and high SNR across a broad bandwidth), and a RoHS-compliant, industrial-temperature package (the IRGZR variant). It supports flexible digital output interfaces for modern back-ends and evaluation kits. When designing, consider input range, reference, power supplies, and proper decoupling. For exact specifications (sampling rate, SNDR, distortion, input bandwidth, voltage rails, pinout), consult the TI datasheet and product page.

Features

ADS4142IRGZR features (concise):
- 14-bit, high-speed ADC
- Differential analog input with selectable input range and common-mode
- High sampling rate (hundreds of MSPS range)
- On-chip sampling/holding and robust front-end
- Flexible digital interface: LVDS or JESD204B serial outputs
- Programmable data formats and alignment options
- Internal reference option with external reference support
- Low power with standby and power-down modes
- Industrial-temperature grade (-40°C to +85°C)
- RoHS-compliant, lead-free package (IRGZR) with compact form factor

Package

Package type: LFCSP (lead-frame chip-scale package) with exposed pad (Pb-free, RoHS-compliant).

Pinout

- Pin count: 32 pins (VQFN/lead-free package, TI suffix IRGZR).
- Function: High-speed analog-to-digital converter (14-bit) with differential input and LVDS/JESD204B-compatible serial data output; includes clock, reset, and power pins for conversion of analog input to digital data.

Manufacturer

Analog Devices, Inc. (ADI) manufactures the ADS4142IRGZR. ADI is an American multinational semiconductor company that designs and markets analog, mixed-signal, and DSP (digital signal processing) integrated circuits.

Application

Applications include high-speed RF/IF sampling for communications and software-defined radios; radar (including automotive radar); high-speed data acquisition and instrumentation; test and measurement equipment; and medical imaging/digitization (e.g., ultrasound).
