LTC1286CS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1286CS8#TRPBF is a micropower, 12-bit successive approximation sampling analog-to-digital converter (ADC) housed in an 8-lead SOIC package. It operates on a single supply voltage ranging from 4.5V to 9V and typically draws 250µA of supply current when converting at a maximum sampling rate of 12.5ksps. The device features a single differential analog input and an on-chip sample-and-hold circuit. Data transfer occurs via a serial interface compatible with SPI and Microwire protocols. During idle periods, the ADC automatically powers down to a typical leakage current of 1nA.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with guaranteed ±3/4LSB maximum differential nonlinearity (DNL).
• Single supply operation from 4.5V to 9V with a typical supply current of 250µA at 12.5ksps.
• Automatic shutdown mode reduces supply current to a typical 1nA when not performing conversions.
• On-chip sample-and-hold and serial port for efficient data transfer over three wires.

Analog To Digital Converters (ADC) Applications

• Battery-operated systems requiring low power consumption.
• Remote data acquisition networks.
• Battery monitoring circuits.
• Temperature measurement applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific ordering suffix #TRPBF corresponds to tape and reel packaging as indicated by the manufacturer's part numbering convention. Confirm that the component meets RoHS compliance standards required for the target assembly process. Ensure the supply voltage range of 4.5V to 9V aligns with the system design constraints before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a single differential input channel and high precision in a small footprint. The LTC1286 is suitable where external reference pins are preferred over internal supply-tied references found in the LTC1298 variant. Ensure the microprocessor interface supports the required serial clock speeds up to 200kHz for optimal conversion timing.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1286/LTC1298 family of micropower sampling ADCs. While the LTC1298 offers a two-channel multiplexer and a fixed 4.5V to 5.5V supply range, the LTC1286 provides a dedicated external reference input and a wider 4.5V to 9V operating range. Both share the same 12-bit SAR architecture and S0-8 package options.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1286CN8 or LTC1286IN8 serve as direct pin-compatible replacements in DIP packages. For tape and reel requirements, verify availability of other suffixes within the LTC1286 series. The LTC1285 and LTC1288 are available as 3V versions but differ in supply voltage specifications and may require circuit adjustments.
