Analog Devices Inc. AD9826KRSZ

Overview

AD9826KRSZ from Analog Devices Inc. is a complete 16-bit imaging signal processor designed to sample, condition, and digitize CCD, CIS, CMOS active pixel sensor, and focal-plane-array signals. The device integrates three analog input channels, input clamp circuitry, correlated double sampling, programmable offset DACs, programmable gain amplifiers, a 3:1 multiplexer, a 16-bit ADC, internal voltage reference, 8-bit multiplexed digital output, and a 3-wire serial control interface.

For engineers reviewing the AD9826KRSZ datasheet, AD9826KRSZ pinout, AD9826KRSZ application, or AD9826KRSZ equivalent, this part is most relevant for flatbed document scanners, digital copiers, multifunction peripherals, infrared imaging systems, and machine-vision signal chains requiring 16-bit image acquisition, RGB channel processing, 1× to 6× programmable gain, ±300 mV offset adjustment, and 28-lead SSOP assembly.

Technical Context

AD9826KRSZ uses a 3-channel architecture for trilinear color CCD arrays, with VINR, VING, and VINB processed through clamp, CDS, offset DAC, and PGA stages before conversion by the shared 16-bit ADC. It supports 3-channel 16-bit operation up to 15 MSPS, 1-channel 16-bit operation up to 12.5 MSPS, and a 2-channel mode for mono sensors with odd/even outputs.

The analog signal chain provides 2.0 V p-p or 4.0 V p-p programmable input range, 1× to 6× PGA gain in 64 steps, ±300 mV programmable offset in 512 steps, and 70 dB channel-to-channel crosstalk at 15 MSPS. AVDD operates from 4.75 V to 5.25 V, while DRVDD supports 3.0 V to 5.25 V digital output operation for 3 V or 5 V logic interfaces.

Key Specifications

Pinout & Package

AD9826KRSZ is supplied in a 28-lead Shrink Small Outline Package [SSOP], package option RS-28, compliant with JEDEC MO-150-AH. The SSOP package uses a 0.65 mm lead pitch with a compact body format, helping imaging front-end boards route analog sensor inputs, ADC clocks, serial-control pins, and byte-wide digital outputs in space-constrained scanner, copier, and machine-vision layouts.

Key Features

• Complete 16-bit imaging analog front end with input clamp, CDS, offset DAC, PGA, MUX, ADC, and digital control interface.
• Three-channel Red, Green, and Blue architecture for trilinear color CCD arrays and color imaging sensors.
• CDS and SHA operating modes for CCD sensors, CIS modules, CMOS active pixel sensors, and focal-plane arrays.
• 1× to 6× programmable gain in 64 steps for image-channel scaling.
• ±300 mV programmable offset in 512 steps for black-level and coarse offset correction.
• 3 V / 5 V digital I/O compatibility with 8-bit multiplexed output data and 3-wire serial register programming.

Applications

Equivalent & Alternatives

When evaluating AD9826KRSZ equivalent devices, engineers should compare ADC resolution, imaging-channel count, CDS and SHA support, input signal range, PGA gain range, offset adjustment range, digital output format, serial-control interface, operating temperature, and SSOP package requirements.

Compared with AD9826KRSZRL, AD9826KRSZ keeps the same imaging signal-processing architecture, pinout, electrical function, operating temperature range, and RS-28 SSOP package. AD9826KRSZ vs AD9826KRSZRL selection depends mainly on procurement packaging, feeder setup, production-volume handling, and sourcing continuity rather than circuit redesign.

Quality

AD9826KRSZ should be sourced as original Analog Devices Inc. components through traceable and controlled supply channels. Quality verification procedures may include SSOP package inspection, top-mark validation, RoHS suffix confirmation, solderability testing, 16-bit ADC function verification, serial-register communication testing, PGA gain and offset programming checks, digital output timing review, and incoming inspection according to imaging signal-chain production requirements.

Availability

AD9826KRSZ is available at Aetrix Electronics and suitable for scanner analog front ends, digital copier image acquisition, infrared imaging platforms, and machine-vision signal processors requiring stable component supply and repeatable production support.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and long-term availability support for OEM manufacturers, imaging-equipment developers, industrial vision designers, and electronics production programs.

For production deployment, confirming the 28-lead SSOP package, 16-bit imaging signal processor function, analog input mode, clock timing, digital output interface, operating temperature range, environmental specifications, and sourcing continuity helps reduce procurement risk and improve manufacturing stability.

Manufacturer

Analog Devices Inc. supplies precision analog, mixed-signal, and imaging signal-processing ICs for measurement, industrial, communication, and sensor-interface systems. The AD9826 family combines CCD/CIS front-end signal conditioning with 16-bit conversion and serial configurability for image acquisition platforms that require integrated analog processing before digital image handling.

FAQ

What is AD9826KRSZ used for?

AD9826KRSZ is used for imaging analog front-end processing in flatbed scanners, digital copiers, multifunction peripherals, infrared imaging systems, and machine-vision equipment. It conditions image-sensor signals and converts them with a 16-bit ADC.

Does AD9826KRSZ support CCD and non-CCD sensors?

Yes. AD9826KRSZ supports correlated double sampling for CCD sensors, and its CDS amplifiers can be disabled for sensors that do not require CDS, including CIS modules, CMOS active pixel sensors, and focal-plane arrays.

What package is used by AD9826KRSZ?

AD9826KRSZ uses a 28-lead SSOP package, package option RS-28. The KRSZ ordering code covers the -40 °C to +85 °C temperature range, SSOP package, and RoHS-compliant Z suffix.

What should be considered in AD9826KRSZ pinout design?

AD9826KRSZ pinout design should separate the analog input paths at VINR, VING, and VINB from digital output switching noise, decouple AVDD, DRVDD, CAPT, CAPB, CML, and OFFSET close to the device, route CDSCLK1, CDSCLK2, and ADCCLK with controlled timing, and connect DRVDD to the required 3 V or 5 V digital output domain.

What is a common AD9826KRSZ equivalent option?

AD9826KRSZRL is the closest ordering alternative because it uses the same AD9826 imaging signal processor, 28-lead SSOP package, and -40 °C to +85 °C operating range, with reel packaging for production assembly.
