AD7884AP

Overview

The AD7884AP is a 16-bit monolithic analog-to-digital converter featuring an internal sample-and-hold amplifier and a two-pass flash architecture. It operates from ±5 V supplies with a 3 V reference input, achieving a maximum throughput rate of 166 kSPS and a conversion time of 5.3 µs. The device provides a 16-bit parallel data output in twos complement code and supports ±5 V or ±3 V analog input ranges. It is housed in a 44-lead Plastic Leaded Chip Carrier (PLCC) package and functions within a temperature range of –40 °C to +85 °C.

Feature Summary

• Two-pass flash architecture for high-speed 16-bit resolution
• Internal oscillator eliminates external clock requirements
• Integrated sample-and-hold amplifier with overlapping acquisition
• Factory-trimmed on-chip segmented DAC for linearity

Applications

• Automatic Test Equipment
• Medical Instrumentation
• Industrial Control Systems
• Data Acquisition Systems
• Robotics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current guide to confirm package type and temperature grade. Ensure the component matches the required linearity and SNR specifications for the intended application environment before finalizing procurement.

Selection Notes

Select this model when a 16-bit resolution and 166 kSPS throughput are required without external clocking. Consider the PLCC package constraints and dual supply requirement (+5 V/–5 V). Verify that the system can accommodate the specified 250 mW power dissipation and 3 V reference voltage.

Part Context

This component belongs to the AD7884/AD7885 family of LC2MOS high-speed sampling ADCs. The AD7884 variant specifically offers a full 16-bit parallel interface, distinguishing it from the byte-read AD7885. Both share identical core conversion performance and architectural features.

Replacement Considerations

Public confirmed substitutes include the AD7885AAP and AD7885ABP, which share equivalent specifications with the AD7884AP and AD7884BP respectively.
