ADS1286UL

Analog To Digital Converters (ADC) Overview

The ADS1286UL is a 12-bit micro-power successive approximation 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 20 kHz sampling rate and communicates via an SPI/SSI compatible serial interface. It operates within a power supply range of 4.5 V to 5.25 V and is housed in an 8-lead SOIC package. The component is specified for operation across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with guaranteed no missing codes

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'UL' against the manufacturer's ordering information to confirm the package type and temperature grade. Ensure that the required quantity aligns with standard packaging options, such as tubes or tape-and-reel variants like ADS1286UL/2K5, if applicable to the design requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low pin count and minimal power consumption are critical constraints. The ADS1286UL is suitable for designs requiring a single-channel differential input without the need for internal reference or programmable gain amplifiers. Verify that the system can accommodate the external reference voltage requirements and the specific timing constraints of the serial interface.

Analog To Digital Converters (ADC) Part Context

The ADS1286UL belongs to the ADS1286 family of 12-bit ADCs from Texas Instruments. This series includes various packages and temperature grades, such as the plastic DIP (ADS1286P) and other SOIC variants (ADS1286U, ADS1286UB). The 'UL' designation specifically identifies the 8-lead SOIC package with the extended industrial temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include ADS1286U, ADS1286UA, ADS1286UB, and ADS1286UC. These parts share identical electrical specifications and pinouts but may differ in package quantity or specific temperature sub-ranges. Verify the exact suffix requirements before substitution.
