ADS7807UE4

Analog To Digital Converters (ADC) Overview

The ADS7807UE4 is a low-power, 16-bit sampling CMOS Analog-to-Digital Converter (ADC) manufactured by Texas Instruments. It utilizes a capacitor-based Successive Approximation Register (SAR) architecture with an integrated sample-and-hold circuit, clock generator, and reference. The device supports parallel and serial data output interfaces and operates on a single +5V supply. Key electrical specifications include a maximum throughput rate of 40 kHz, a complete cycle time of 25 µs, and a maximum power dissipation of 35 mW. It offers integral linearity error of ±1.5 LSB and differential linearity error of +1.5/-1 LSB without missing codes. The ADC provides standard industrial input ranges of ±10V, 0V to +5V, and 0V to +4V.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. The 'U' designation typically indicates an SO-28 surface-mount package, while other suffixes may denote DIP variants. Ensure compatibility with required input range configurations and interface timing constraints before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 40 kHz throughput are required in a low-power form factor. Consider the available input ranges and interface requirements; the device supports both parallel and serial outputs. Verify that the system can accommodate the specified power supply voltages and thermal conditions within the -40°C to +85°C operating range.

Analog To Digital Converters (ADC) Part Context

The ADS7807 belongs to the ADS780x family of low-power, high-resolution ADCs from Texas Instruments. It is pin-compatible with the 12-bit ADS7806, facilitating upgrades in existing designs. The device is designed for applications demanding precise analog-to-digital conversion with minimal power consumption and flexible digital interfacing options.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7807 is pin-compatible with the ADS7806. For higher resolution requirements, consider the ADS8507 series. Verify that any substitute maintains the 16-bit resolution, 40 kHz throughput, and compatible package dimensions.
