ADS7828EB/2K5G4

Analog To Digital Converters (ADC) Overview

The ADS7828EB/2K5G4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an 8-channel multiplexer supporting pseudo-differential or single-ended inputs, with a sampling rate of 50 kSPS. The device operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. It utilizes an I2C-compatible serial interface for data communication. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of -1/2 LSB, and integral nonlinearity of +/- 1 LSB. Power consumption is specified at 675 uW during operation, with a maximum power dissipation of 5 mW. The component is available in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the /2K5 designation corresponds to the standard tape-and-reel packaging quantity of 2,500 units. Ensure the E variant matches the required linearity specifications compared to other ADS7828 family members. Cross-reference the datasheet revision date to confirm current design parameters before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel input solution is required within a compact surface-mount footprint. The I2C interface reduces pin count compared to SPI alternatives, simplifying PCB layout. Verify that the 50 kSPS sampling rate meets the bandwidth requirements of the target application. Consider the internal reference option if external precision voltage sources are unavailable or cost-prohibitive.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7828 family of micro-power ADCs designed for battery-operated applications. It shares architectural similarities with the ADS7823 and ADS7822 but offers higher channel density. The device complements Texas Instruments' portfolio of low-speed, high-precision data converters suitable for sensor interfacing.
