That combination — 20-bit resolution at a megasample per second — puts it in a narrow performance band: you get the dynamic range of a precision converter without giving up the throughput needed for fast-scanning data-acquisition systems, vibration analysis, or high-speed closed-loop control. The SPI interface keeps the digital side simple, and the external reference gives you control over the full-scale range and noise floor. ## Supply and interface — what to budget on the board Both the analog and digital supplies run from 2.375 V to 2.625 V. The SPI interface operates at the same digital supply level. ## Lifecycle and sourcing — active, no LTB watch needed The LTC2378CDE-20#PBF carries an Active lifecycle status. For a 20-bit, 1 MSPS ADC, that is a useful assurance: precision converters in this speed class often get superseded, but this one is still a supported catalog line.","metaTitle":"LTC2378CDE-20#PBF ADC 20-Bit SAR 1 MSPS, 16-DFN","metaDescription":"LTC2378CDE-20#PBF 20-bit SAR ADC, 1 MSPS, differential input, SPI interface, 16-DFN package.

The AD7982BRMZRL7 is an 18-bit, 1 MSPS differential SAR ADC from the same functional class, but it is two bits lower in resolution and has a different pinout and reference scheme. For a 20-bit, 1 MSPS differential SAR ADC, the LTC2378CDE-20#PBF is the primary choice."},{"question":"Can LTC2378CDE-20#PBF be used with a 3.3V SPI interface?","answer":"The digital supply range is 2.375 V to 2.625 V, so a 3.3 V SPI host requires level translation on the SPI lines.
