Overview
The AD7880CNZ is a monolithic 12-bit analog-to-digital converter (ADC) fabricated in Analog Devices' LC2MOS process. It operates from a single +5 V supply and features a successive-approximation architecture with a throughput rate of 66 kS/s. The device integrates a 3 μs track/hold amplifier and a 12 μs conversion time, resulting in a total throughput of 15 μs. Key electrical specifications include a signal-to-noise ratio of 70 dB, ±1 LSB integral and differential nonlinearity, and a typical power dissipation of 25 mW in normal operation. It supports three user-defined input ranges: 0 to 5 V, 0 to 10 V, and ±5 V.

Procurement Notes
Verify the specific suffix 'CNZ' against the manufacturer's current ordering guide to confirm package type and temperature range compliance. Confirm availability status as distribution channels may list limited stock or obsolete status for this specific part number variant.
Selection Notes
Select the AD7880CNZ when a single-supply 12-bit ADC with parallel output is required. Ensure the application supports a 2.5 MHz clock input and utilizes standard TTL/CMOS logic levels for control signals. Verify that the required input voltage range matches the internal attenuator network configurations provided in the datasheet.
Part Context
The AD7880CNZ belongs to the AD7880 family of high-speed, low-power sampling ADCs. This series is designed for applications requiring moderate resolution and fast data acquisition rates while maintaining low power consumption. The CNZ designation typically indicates a plastic DIP package with industrial temperature range specifications.
Replacement Considerations
Check the Ordering Guide for alternative packages such as SOIC (R suffix) or CerDIP (Q suffix). Consider the AD7880BNZ or AD7880BRZ if different accuracy grades or packaging options are required.
