LTC1282BCSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1282BCSW#TRPBF is a 140ksps, 12-bit sampling analog-to-digital converter featuring an integrated precision reference. It operates from a single 3V or dual ±3V supply with typical power dissipation of 12mW. The device utilizes LTBiCMOS switched capacitor technology and includes a 1.14µs sample-and-hold circuit with an internally trimmed clock. Maximum DC specifications include ±0.5LSB INL and ±0.75LSB DNL for the B grade. AC performance provides 69dB S/(N + D) and 77dB THD at the Nyquist frequency of 70kHz. It supports unipolar (0V to 2.5V) and bipolar (±1.25V) input ranges.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the BC suffix corresponds to the commercial grade temperature range of 0°C to 70°C as defined in the manufacturer's order information table. Ensure compatibility with the 24-lead plastic SO Wide package dimensions during PCB layout planning.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1282BCSW#TRPBF for applications requiring high throughput rates up to 140ksps with low power consumption. The B grade offers tighter linearity specifications compared to the A grade. Consider the internal reference stability and the need for external buffering if driving the VREF pin with significant load currents beyond the specified limits.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1282 series of 12-bit sampling ADCs manufactured by Analog Devices Inc.
