Product details
Overview
ADS5562IRGZT from Texas Instruments is a 16-bit, 80 MSPS analog-to-digital converter with DDR LVDS and CMOS output interfaces, internal/external reference support, and low-frequency noise suppression mode. It features 84 dBFS SNR at 3 MHz IF, 85 dBc SFDR, and operates from 3.3-V analog/digital supplies in industrial temperature range (–40°C to 85°C) for high-fidelity signal acquisition in MRI front-ends.
For engineers reviewing the ADS5562IRGZT datasheet, ADS5562IRGZT pinout, ADS5562IRGZT application, or ADS5562IRGZT equivalent, key selection criteria include its 80 MSPS sampling rate, DDR LVDS output architecture, programmable fine gain (1-dB steps up to 6 dB), 300-MHz analog input bandwidth, and 48-pin VQFN package with exposed thermal pad for thermal management in dense PCB layouts.
Technical Context
The ADS5562IRGZT integrates a high-linearity sample-and-hold stage, 16-bit SAR or pipeline architecture (per TI documentation), and dual-mode digital interface configurable via DFS and MODE pins. Its internal reference eliminates external decoupling capacitors, while the VCM pin serves as either common-mode voltage output or external reference input depending on MODE state.
It supports two operational modes: DEFAULT SPEED (>25 MSPS) and LOW SPEED (1–25 MSPS), with automatic power scaling and STANDBY mode reducing total power to 135 mW. Clock inputs accept differential LVDS, LVPECL, or LVCMOS waveforms, and the device provides CLKOUTP/CLKOUTM for clock forwarding in synchronous systems.

FAQ
What is the maximum sampling rate supported by the ADS5562IRGZT?
The ADS5562IRGZT supports a maximum sampling rate of 80 MSPS in DEFAULT SPEED mode. This is confirmed in the datasheet's Features section and AC Electrical Characteristics table for ADS5562. At this rate, it maintains 84 dBFS SNR and 85 dBc SFDR at 3 MHz input frequency, making ADS5562IRGZT suitable for demanding wideband digitization tasks.
Does the ADS5562IRGZT require external decoupling capacitors for its internal reference?
No, the ADS5562IRGZT does not require external decoupling capacitors for its internal reference. As stated in the datasheet Features section, "internal reference that does not require external decoupling capacitors" is a key innovation enabling pin count reduction. This design simplifies layout and reduces BOM cost while maintaining stability across the industrial temperature range for ADS5562IRGZT.
How is the output interface mode (LVDS vs. CMOS) selected on the ADS5562IRGZT?
The output interface mode on ADS5562IRGZT is selected using the DFS pin, as documented in Pin Functions and Table 7 of the datasheet. When DFS is low, the device operates in LVDS mode; when high, it configures for CMOS output. The MODE pin simultaneously selects internal/external reference, and both pins must be set during power-up to establish the intended ADS5562IRGZT configuration.
What is the purpose of the OVR pin on the ADS5562IRGZT?
On the ADS5562IRGZT, the OVR (Out-of-Range) pin is a CMOS-level indicator that asserts high when the analog input exceeds the full-scale range. Per the Pin Functions table, it provides real-time overrange detection without requiring software polling. This allows immediate system response-such as gain adjustment or signal path muting-to prevent data corruption, enhancing reliability in ADS5562IRGZT-based acquisition systems.
Can the ADS5562IRGZT operate with an external reference, and how is it configured?
Yes, the ADS5562IRGZT supports external reference operation. Configuration is achieved by setting the MODE pin low (internal pulldown), which reassigns the VCM pin from common-mode output to external reference input. The datasheet specifies a valid input range of 1.5 ±0.05 V for VCM in this mode. This flexibility allows system designers to synchronize ADS5562IRGZT with precision external references for improved channel matching in multi-ADC arrays.
