Datasheet
The AD1376/AD1377 is a 16-bit high resolution analog-to-digital converter with internal reference, clock, and laser-trimmed thin-film application resistors. The AD1376/AD1377 are excellent for use in high resolution applications requiring moderate speed and high accuracy or stability over commercial temperature ranges (0°C to 70°C). They are packaged in compact 32-lead, ceramic seam-sealed (hermetic), dual in-line packages.
