ADS7865IPBSG4

Analog To Digital Converters (ADC) Overview

The ADS7865IPBSG4 is a dual, simultaneous-sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features two independent 12-bit Successive Approximation Register (SAR) converters operating at a sampling rate of 2 MSPS. The device supports differential or pseudo-differential inputs and utilizes a parallel interface for data output. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 71.7 dB and a SINAD of 71.3 dB. Differential Nonlinearity (DNL) is specified at +/- 1 LSB, while Integral Nonlinearity (INL) is +/- 1.25 LSB. The component is housed in a 32-pin TQFP package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the datasheet revision date to confirm pinout compatibility with existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is critical for applications like motor control or power monitoring. The 12-bit resolution and 2 MSPS speed balance precision with throughput. Consider the TQFP-32 package constraints and parallel interface requirements during schematic design. Verify that the system power supply remains within the 2.7 V to 5.5 V operational range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7865 family of dual ADCs. The 'G4' suffix typically indicates a lead-free and RoHS-compliant version of the standard ADS7865IPBS. It shares core electrical characteristics with other variants in the series but may differ in environmental compliance certifications. The IPBS designation confirms the 32-pin Thin Quad Flatpack (TQFP) package style.
