ADS7961SDBTRG4

Analog To Digital Converters (ADC) Overview

The ADS7961SDBTRG4 is a 12-bit, 1MSPS, 4-channel, single-ended, micro-power, serial interface SAR ADC manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.7V to 5.5V and features a high-speed successive approximation register architecture. The device integrates a track-and-hold amplifier for each channel and supports both standard SPI and QSPI interfaces. It is designed for low-power applications requiring high throughput and accuracy in a compact TSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• High-speed 1MSPS sampling rate with 12-bit resolution
• Low power consumption suitable for battery-operated systems
• Flexible serial interface compatible with standard SPI and QSPI protocols
• Integrated track-and-hold circuitry for four single-ended channels

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Data acquisition systems
• Battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the package marking and date code align with current production standards. Ensure the ordering part number matches the exact pin count and thermal pad requirements for the TSSOP-30 footprint during PCB design review.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four single-ended inputs are required at 1MSPS with 12-bit precision. Compare against the ADS7950 series if differential inputs are needed instead. Consider the operating temperature range and supply voltage constraints relative to the system's power budget. Verify interface compatibility with the host microcontroller's SPI controller capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS796x family of 12-bit, 1MSPS analog-to-digital converters. It shares architectural similarities with the ADS7950 but differs in input configuration and specific feature sets. The family is designed for general-purpose data acquisition applications requiring moderate speed and resolution. The 'G4' suffix denotes lead-free and RoHS compliant manufacturing processes consistent with Texas Instruments' environmental standards.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7950SBDBT is a pin-compatible alternative within the same family offering similar performance characteristics. Verify that the input type (single-ended vs. differential) meets the application requirements before substitution. Check for any differences in power consumption or interface timing specifications between the two variants.
