AD7813YN

Overview

The AD7813YN is an 8-/10-bit successive approximation analog-to-digital converter featuring a maximum throughput of 400 kSPS. It operates from a single 2.7 V to 5.5 V supply and integrates a 2.3 µs SAR core, track/hold circuitry, and an on-chip clock oscillator. The device utilizes an 8-bit wide parallel interface designed for microprocessor compatibility. Power consumption is 10.5 mW at 3 V in normal operation, reducing to 34.6 µW at 1 kSPS via automatic power-down. It guarantees no missing codes over the specified temperature range.

Feature Summary

• Integrates an on-chip clock oscillator and track/hold circuitry for simplified system design
• Features an 8-bit wide parallel interface compatible with standard microprocessors and DSPs
• Supports automatic power-down mode to significantly reduce average power consumption at lower sampling rates

Applications

• Microprocessor-based data acquisition systems
• Battery-powered instrumentation requiring low power consumption
• Industrial process control applications

Procurement Notes

Verify the specific package variant when ordering, as the base model number corresponds to multiple physical packages. The AD7813YN designation specifically indicates the plastic dual-in-line package (DIP-16). Confirm that the required operating voltage range and interface timing align with the target microcontroller specifications before finalizing procurement.

Selection Notes

Select this component for applications requiring high-speed conversion up to 400 kSPS with a simple parallel interface. It is suitable for designs needing a single supply voltage between 2.7 V and 5.5 V. Consider the DIP-16 package constraints if board space is limited, or evaluate alternative package options like SOIC or TSSOP if surface mount technology is preferred for the assembly process.

Part Context

The AD7813 belongs to Analog Devices' family of high-speed, microprocessor-compatible sampling ADCs. It is part of the AD7813 series, which includes variants with different packaging options such as the SOIC and TSSOP. This specific part represents the through-hole DIP version within that product line.

Replacement Considerations

Direct pin-compatible replacements include the AD7813YR (SOIC-16) and AD7813YRU (TSSOP-16), which share identical electrical characteristics but differ in physical package dimensions.
