ADS7954SDBTR

Analog To Digital Converters (ADC) Overview

The ADS7954SDBTR is a 10-bit, 4-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It operates with a sampling rate of 1 MSPS and supports single-ended inputs. The device features an SPI-compatible serial interface for data output. It functions within an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 1.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 60 dB and a total power consumption of 11.5 mW. Differential nonlinearity (DNL) and integral nonlinearity (INL) are specified at +/- 0.5 LSB. The component is housed in a TSSOP-30 package and is rated for operation between -40°C and +125°C.

Analog To Digital Converters (ADC) Feature Summary

• MicroPower architecture enabling low energy consumption suitable for battery-operated systems
• Single-ended input configuration with multiplexer support for four channels
• Flexible dual-supply operation allowing independent analog and digital voltage domains

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring low power and moderate resolution
• Industrial process control systems with single-ended sensor interfaces
• Data acquisition modules in embedded monitoring applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the ordering part number matches the exact pin count and package dimensions required for the target PCB layout. Cross-reference the manufacturer's latest revision history to confirm material and functional consistency.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 10-bit resolution and 1 MSPS throughput is required for single-ended signals. Compare against the ADS7950 series if higher 12-bit resolution is necessary, noting potential differences in linearity specifications. Evaluate the ADS7955 variant if eight input channels are needed instead of four. Ensure the external reference voltage capability aligns with system accuracy requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the Texas Instruments microPOWER ADC family, designed for low-power data conversion tasks. It shares architectural similarities with the ADS7950, ADS7951, and ADS7953 models, differing primarily in resolution and channel count. The SDBTR designation specifies the surface-mount TSSOP-30 package with tape-and-reel shipping format for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7954SDBT is the tube-packaged equivalent of the same electrical device. ADS7950SDBTR offers 12-bit resolution with similar speed and channel count. ADS7955SDBTR provides 10-bit resolution but increases channel count to eight.
