AD80066KRSZ

Overview

The AD80066KRSZ is a complete 16-bit analog signal processor for imaging applications, featuring a 24 MSPS ADC and four-channel architecture. It samples and conditions outputs from linear CCD or CIS arrays using input clamp, correlated double sampling (CDS), programmable gain amplifier (PGA), and offset DAC blocks. The device supports selectable input ranges of 3 V or 1.5 V peak-to-peak and offers 1× to 5.9× programmable gain with ±300 mV offset adjustment. Digital output is multiplexed into an 8-bit word via a 3-wire serial interface, compatible with 3 V/5 V logic. Power dissipation is typically 490 mW at 24 MHz operation in a 28-lead SSOP package.

Feature Summary

• Integrated 16-bit ADC with up to 24 MSPS conversion rate across configurable channel modes
• Programmable gain amplifiers and offset digital-to-analog converters for precise signal conditioning
• Correlated double sampling circuitry with selectable input range and internal voltage reference
• Multiplexed byte-wide digital output accessible through a 3-wire serial control interface

Applications

• Flatbed document scanners
• Film scanners
• Digital color copiers
• Multifunction peripherals

Procurement Notes

Verify the specific ordering suffix KRSZ against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as specifications are subject to change without notice. Ensure the component meets the required operating temperature range for the intended application environment before finalizing procurement.

Selection Notes

Select this component when designing systems requiring high-resolution imaging signal processing for CCD or CIS sensors. Evaluate the power consumption requirements, noting that slow power mode reduces dissipation at lower clock speeds. Verify that the available PGA gain steps and offset resolution meet the dynamic range needs of the specific sensor array being utilized.

Part Context

The AD80066KRSZ belongs to the Analog Devices AD80066 family of complete CCD/CIS signal processors. This series integrates analog front-end conditioning with high-resolution digitization to simplify scanner and copier designs. The KRSZ designation specifically identifies the 28-lead SSOP package variant within the broader product line.
