LTC1863LCGN#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1863LCGN#TRPBF is an 8-channel, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) operating at a sampling rate of 175ksps. It features a single-ended or differential input multiplexer with unipolar (0V to 2.5V) and bipolar (±1.25V) conversion modes. The device operates on a single 2.7V supply, drawing 750µA at full speed. It includes an internal 1.25V reference, SPI/MICROWIRE serial interface, and automatic nap mode reducing current to 170µA. Housed in a 16-lead narrow SSOP package, it supports industrial temperature ranges.

Analog To Digital Converters (ADC) Feature Summary

• 8-channel multiplexer supporting single-ended and differential configurations
• Low power consumption with automatic nap and sleep modes
• Integrated 1.25V precision reference with external override capability
• SPI/MICROWIRE compatible serial digital interface

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• High-speed data acquisition applications
• Battery-operated portable instrumentation
• Multiplexed sensor networks
• Imaging system signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix matches the required temperature grade and packaging format. The #TRPBF suffix indicates tape and reel packaging for surface mount assembly. Confirm that the LC variant meets the commercial temperature range requirements for the target application environment before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when space-constrained designs require multiple analog inputs without external multiplexers. The 12-bit resolution suits general-purpose sensing where 16-bit accuracy is unnecessary. Ensure the driving circuit impedance allows for the specified 2.01µs acquisition time to maintain linearity specifications across the full operating temperature range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1863L/LTC1867L family of micropower, 3V ADCs. It is pin-compatible with the standard voltage LTC1863/LTC1867 series but optimized for lower voltage operation starting at 2.7V. The 'L' designation indicates low-voltage support, while 'C' denotes the commercial temperature grade within the narrow SSOP package lineup.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include the LTC1863IGN#TRPBF for wider temperature ranges or the LTC1867LCGN#TRPBF for higher 16-bit resolution. Verify that the replacement maintains compatibility with the existing serial interface timing and reference configuration constraints.
