ADS1286UK

Analog To Digital Converters (ADC) Overview

The ADS1286UK is a 12-bit micro-power sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a differential input with an integrated sample and hold amplifier, consuming only 250 μA of supply current. The device supports a maximum sampling rate of 20 kHz and utilizes an SPI/SSI compatible serial interface for communication over two or three wires. Designed for low power applications, it operates within a temperature range of -20°C to +70°C and is housed in an 8-lead SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix UK indicates the commercial temperature grade (-20°C to +70°C) and SOIC-8 packaging. Confirm ordering quantities match the tube (100 units) or reel (2500 units) options available for this part number. Ensure compatibility with existing design specifications regarding voltage levels and interface requirements.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS1286UK when a 12-bit resolution and 20 kHz sampling rate are sufficient for the application. Consider this part for designs requiring low power consumption and isolation capabilities due to its serial interface. Verify that the commercial temperature range meets the environmental requirements of the target system.

Analog To Digital Converters (ADC) Part Context

The ADS1286UK belongs to the ADS1286 family of 12-bit ADCs from Texas Instruments. This family includes variants with different temperature ranges and packaging options, such as the ADS1286UB for industrial temperatures (-40°C to +85°C). The UK suffix specifically denotes the commercial grade operating temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1286UB serves as a direct replacement for higher temperature requirements (-40°C to +85°C). Other ADS1286 variants with different suffixes may offer alternative packaging or temperature grades but maintain functional compatibility.
