LTC1282ACSW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1282ACSW#PBF is a 140ksps, 12-bit sampling analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 3V or dual ±3V supply with typical power dissipation of 12mW. The device features an internal 1.20V reference and internally trimmed clock. Unipolar mode supports 0V to 2.5V inputs; bipolar mode supports ±1.25V inputs with two's complement output. Maximum DC specifications include ±0.5LSB INL, ±0.75LSB DNL, and 25ppm/°C full-scale drift. AC performance includes 69dB S/(N + D) and 77dB THD at the Nyquist frequency of 70kHz.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component matches the specific A-grade commercial temperature range (0°C to 70°C). Confirm the package type is the 24-lead plastic SO Wide. Ensure the ordering suffix corresponds to the lead-free finish tape and reel variant if required for automated assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 140ksps throughput rate and 12-bit resolution are required within a 3V system. The internal reference simplifies design by eliminating external components. Consider the bipolar input capability if negative voltage signals must be digitized directly without additional level shifting circuitry.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1282 series of 12-bit sampling ADCs. The 'A' grade indicates tighter linearity specifications compared to the 'B' grade. The SW suffix denotes the 24-lead plastic SO Wide package. The #PBF suffix identifies the lead-free finish version compliant with RoHS standards.
