AD9040AJN

Overview

The AD9040AJN is a complete 10-bit monolithic sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It integrates an on-board track-and-hold circuit and voltage reference, requiring only an encode signal to achieve sample rates of 40 MSPS with 10-bit resolution. The device is designed for low-cost, high-performance applications, consuming 940 mW of power while delivering a signal-to-noise ratio (SNR) of 53 dB at a 10 MHz analog input frequency. It features CMOS-compatible digital outputs and accepts a fully characterized 2 V peak-to-peak analog input signal.

Feature Summary

• Integrates on-board track-and-hold and reference circuits
• CMOS-compatible digital interface
• Low power consumption design

Applications

• Ultrasound medical imaging
• Digital oscilloscopes
• Professional video systems
• Digital communications
• Advanced television MUSE decoders

Part Context

The AD9040AJN belongs to the AD9040A family of high-speed ADCs from Analog Devices. This series includes variants such as the AD9040APWB and AD9050, which share similar 10-bit, 40 MSPS specifications. The AJN suffix typically denotes a specific package and temperature range variant within this product line, distinct from other packaging options like PWB.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pinout and electrical compatibility if considering alternatives from the same manufacturer or other vendors offering 10-bit, 40 MSPS ADCs.
