ADS7953SBRHBR

Analog To Digital Converters (ADC) Overview

The ADS7953SBRHBR is a 12-bit, 1-MSPS, 16-channel single-ended microPower SAR ADC manufactured by Texas Instruments. It features an SPI serial interface and operates with analog supply voltages from 2.7 V to 5.25 V and digital supply voltages from 1.7 V to 5.25 V. The device achieves a signal-to-noise ratio (SNR) of 71.7 dB and has a power consumption of 11.5 mW. It utilizes an external reference voltage of 2.5 V and exhibits an integral nonlinearity (INL) of 0.024% FSR. The component is housed in a VQFN-32 package and supports operating temperatures between -40°C and +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Provides high-speed data acquisition with a 1 MSPS sampling rate across 16 single-ended channels.
• Enables direct interfacing with CMOS digital hosts through a wide 1.7 V to 5.25 V I/O supply range.
• Supports low-power operation suitable for battery-supplied systems with 11.5 mW power consumption.

Analog To Digital Converters (ADC) Applications

• Battery-supplied systems
• Isolated power supply monitoring
• Medical instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BR' against the manufacturer's official datasheet to confirm it denotes the tape-and-reel packaging variant rather than a functional difference. Ensure the order matches the required VQFN-32 package configuration. Confirm RoHS compliance status directly with the supplier documentation before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this part when a 16-channel multiplexed input is required alongside a 1 MSPS conversion speed. The VQFN-32 package is appropriate for space-constrained designs requiring surface-mount installation. Verify that the application requires single-ended inputs and can accommodate the specified analog and digital supply voltage ranges.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS7953 family of 12/10/8-bit multi-channel analog-to-digital converters. It shares core specifications with variants like the ADS7953SBRHBT but differs in packaging or reel configuration. The series is designed for applications needing multiple single-ended inputs with low power consumption and high throughput.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7953SBRHBT is a confirmed substitute within the same family, offering identical electrical performance. Other compatible options include the ADS7953SBDBTR, which provides the same functionality in a TSSOP-38 package. Ensure pin compatibility and thermal requirements are met when switching packages.
