AD7845TE/883B

Overview

The AD7845TE/883B is a high-reliability, military-grade 12-bit Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. under the MIL-PRF-38534 specification. It features a CMOS multiplying architecture with an R-2R ladder network and integrated output buffer. The device accepts parallel binary input data and provides a buffered voltage output capable of swinging between positive and negative supply rails, typically ±10V. Designed for harsh environments, it offers precise linearity and fast settling times suitable for demanding aerospace and defense applications requiring verified radiation hardness and extended temperature stability.

Feature Summary

12-bit resolution with multiplying DAC architecture
MIL-PRF-38534 qualified for military/aerospace reliability
Parallel digital interface with latchable inputs
Integrated buffered voltage output stage

Applications

Aerospace guidance and control systems
Military radar signal processing
High-reliability industrial instrumentation
Defense communication equipment

Part Context

This component belongs to the AD7845 family of multiplying DACs. The '/883B' suffix denotes compliance with MIL-PRF-38534, indicating it is a screened version of the standard AD7845 designed for long-term availability and strict quality control in defense contracts. It is distinct from commercial variants due to its enhanced testing and traceability requirements.

Replacement Considerations

Direct pin-compatible replacements include the standard commercial AD7845 series (e.g., AD7845JPZ, AD7845ARZ) if military qualification is not required. For equivalent performance without the '/883B' screening, verify that the commercial grade meets the specific environmental and reliability standards of the application.
