AD9200ARSZ

Overview

The AD9200ARSZ is a monolithic, single-supply, 10-bit analog-to-digital converter featuring a 20 MSPS sampling rate and an on-chip sample-and-hold amplifier. It utilizes a multistage differential pipeline architecture to guarantee no missing codes across the industrial temperature range of –40°C to +85°C. The device operates within a supply voltage range of 2.7 V to 5.5 V, consuming 80 mW at 3 V. Key specifications include a differential nonlinearity (DNL) of 0.5 LSB, an integral nonlinearity (INL) of 0.75 LSB typical, and a signal-to-noise ratio (SNR) of 57 dB at 3.58 MHz. It supports both single-ended and differential inputs and includes an out-of-range indicator.

Feature Summary

• Multistage differential pipeline architecture ensures high-speed conversion with low power consumption.
• On-chip programmable voltage reference allows flexible input span configurations.
• Built-in clamp function enables DC restoration for AC-coupled video signals.
• Pin-compatible with legacy AD876 designs to facilitate migration to lower supply voltages.

Applications

• Imaging systems requiring high-speed data acquisition
• Communications systems utilizing IF undersampling
• Portable instrumentation with strict power constraints

Procurement Notes

Verify the specific suffix 'ARSZ' confirms the industrial temperature grade (-40°C to +85°C) and SSOP-28 package. Confirm RoHS compliance status with the manufacturer or authorized distributor prior to ordering. Ensure the design accounts for the required decoupling capacitors on reference pins as specified in the datasheet application circuits.

Selection Notes

Select this component when a 10-bit resolution at 20 MSPS is required with minimal power dissipation. Consider the internal reference capabilities if external precision references are undesirable. Verify that the input signal range aligns with the configurable 1 V or 2 V spans. Check pin compatibility requirements if replacing older AD876 designs.

Part Context

The AD9200ARSZ belongs to the Analog Devices AD9200 family of CMOS A/D converters. This series is characterized by its pipeline architecture designed for portable applications. The ARSZ variant specifically denotes the industrial temperature range and shrink small outline package, distinguishing it from commercial variants like the JRSZ.

Replacement Considerations

The AD9200JRSZ serves as a direct pin-compatible replacement offering identical electrical performance but limited to the commercial temperature range (0°C to +70°C). Designers migrating from AD876 should verify that the lower supply voltage operation of the AD9200 meets their system power requirements.
