AD9203WARUZ

Overview

The AD9203WARUZ is a monolithic, low-power, single-supply 10-bit analog-to-digital converter with an on-chip voltage reference. It utilizes a multistage differential pipeline architecture and guarantees no missing codes over the full operating temperature range of -40°C to +85°C. The device operates on a supply voltage between 2.7 V and 3.6 V, consuming 74 mW at 40 MSPS. It features an adjustable input range from 1 V to 2 V p-p for both differential and single-ended inputs. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 59.5 dB at 20 MHz and an Effective Number of Bits (ENOB) of 9.55 bits. The component is qualified for automotive applications and housed in a 28-lead TSSOP package.

Feature Summary

• Qualified for automotive applications with controlled manufacturing standards.
• Features an internal programmable voltage reference with external reference capability.
• Includes an out-of-range indicator signal to detect overflow conditions.
• Supports adjustable power consumption via an external resistor for lower sampling rates.

Applications

• Automotive systems
• Video processing
• Portable instrumentation
• IF and baseband communications

Procurement Notes

Verify that the specific part number suffix matches the required packaging configuration, as tube and reel options exist within the same family. Confirm RoHS compliance status through official documentation. Ensure the automotive qualification requirements align with project specifications before finalizing procurement orders.

Selection Notes

Select this component when automotive reliability is required alongside low power consumption. Consider the adjustable input span if signal conditioning flexibility is needed. Evaluate the ENOB performance against system dynamic range requirements at the target clock frequency. Verify thermal dissipation capabilities within the 28-lead TSSOP package for the intended operating environment.

Part Context

This model belongs to the AD9203 series, which includes commercial variants without the 'W' suffix. The 'W' designation specifically indicates automotive qualification. The 'RUZ' suffix denotes the 28-lead TSSOP package type with RoHS compliance. Other variants may offer different packaging formats such as tape and reel configurations.

Replacement Considerations

Direct replacements within the AD9203 family include AD9203ARUZRL7. Verify pin compatibility and electrical specifications carefully, as commercial and automotive grades may have differing parameter limits. Cross-reference datasheets to ensure functional equivalence in the specific application context.
