AD7346ASTZ-RL

Overview

The AD7346ASTZ-RL is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices. It operates from a single +5 V supply and features a throughput rate of 1 MSPS per channel. The device includes an internal 2.5 V reference and supports serial interface communication compatible with standard microprocessors. It is housed in a 20-lead TSSOP package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel 12-bit SAR ADC architecture
• 1 MSPS sampling rate per channel
• Internal 2.5 V reference voltage
• Single +5 V power supply operation

Applications

• Industrial process control
• Data acquisition systems
• Portable instrumentation

Procurement Notes

Verify the specific suffix 'ASTZ-RL' against official Analog Devices documentation to confirm the temperature grade, lead-free status, and reel packaging quantity. Ensure compatibility with existing board layouts for the 20-lead TSSOP footprint before procurement.

Selection Notes

Select this component when dual-channel 12-bit resolution at 1 MSPS is required with a single 5 V supply. Compare against the AD7344/AD7345 series if higher resolution or different input configurations are needed. Verify interface timing requirements against the target microcontroller.

Part Context

This part belongs to the AD734x family of low-power, high-speed ADCs. It shares architectural similarities with the AD7344 and AD7345 but offers dual channels instead of single or quad configurations. The 'RL' suffix indicates tape and reel packaging for automated assembly.

Replacement Considerations

Direct pin-compatible replacements include other members of the AD734x family such as the AD7344 or AD7345, provided the channel count and resolution meet system requirements. Verify electrical specifications match exactly before substitution.
