The DAC8420 is a quad, 12-bit, voltage-output DAC with serial digital interface in a 16-lead package. It features unusually high circuit density and low power consumption. The simple, easy-to-use serial digital input and fully buffered analog voltage outputs require no external components to achieve specified performance.
The DAC8420 is a quad, 12‑bit voltage‑output DAC with a serial digital interface. It uses BiCMOS technology for high density and low power, and provides fully buffered analog outputs that require no external components. The device operates from a single +5 V supply up to +15 V and supports both unipolar and bipolar output ranges.
The datasheet includes detailed electrical characteristics, absolute maximum ratings, pin configurations, timing diagrams, and programming information. It also lists ordering options for PDIP, CERDIP, and SOIC packages, and provides guidance on using the CLR and CLSEL control pins for zero‑scale or mid‑scale resets.
