ADS7263SRHBT

Analog To Digital Converters (ADC) Overview

The ADS7263SRHBT is a dual-channel, 14-bit Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) manufactured by Texas Instruments. It operates with a maximum sampling rate of 1 MSPS per channel and supports simultaneous sampling for both channels. The device features a 32-pin VQFN package with dimensions of 5x5 mm. It accepts differential or pseudo-differential analog inputs and communicates via an SPI digital interface. Power requirements include an analog supply voltage range of 2.7V to 5.5V and a digital supply voltage range of 2.3V to 5.5V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 85 dB and a power dissipation of 47.2 mW. The component is rated for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RHBT' corresponds to the 32-VQFN package and reel/cut-tape packaging format. Confirm RoHS compliance status and Moisture Sensitivity Level (MSL 3) requirements for your assembly line. Ensure the ordering part number matches the exact pinout and electrical specifications listed in the official datasheet before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel sampling is required without external synchronization circuitry. The 14-bit resolution and 1 MSPS speed suit applications balancing precision and throughput. Consider the dual supply voltage ranges if interfacing with mixed-voltage logic systems. Evaluate the 32-VQFN footprint against available PCB space constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7263 family of dual-channel SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS7250 and ADS7279 but offers higher resolution and simultaneous sampling capabilities. The device complements single-channel variants like the ADS7262 by providing integrated dual-channel performance in a compact form factor.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Verify compatibility with alternative TI models such as the ADS7262 or ADS7251 based on specific resolution and channel count requirements.
