HT82V47

4-Channel, 16-Bit, 60MSPS

CIS Analog Signal Processor

Features

General Description

• 3.3V operating voltage

The HT82V47 is a fully integrated device for CIS

imaging applications. It features a high performance

16-bit 4-channel 60MSPS analog signal processor to

sample and condition the outputs of CIS (Contact Image

Sensor) array for high speed scanner applications.

• Up to 60MSPS for 4-channel inputs

• Support cascade mode for up to 8-channel inputs

• Support line-by-line operation

• 7-bit programmable gain ampliﬁer

• 8-bit programmable oﬀset adjustment

• 6-bit programmable reference bias

• 8/4-bit multiplexed for 16-bit data output

• Internal voltage reference

Each channel consists of a Sample and Hold Ampliﬁer,

SHA, a 7-bit Programmable Gain Ampliﬁer, PGA, and

an 8-bit oﬀset correction Digital to Analog Converter,

DAC. The PGA and offset DAC are programmed

independently allowing unique values of gain and

oﬀset for the 4-channel analog inputs. The 4-channel

signals are routed to a 60MHz high performance

Analog to Digital Converter, ADC. The high

performance 16-bit A/D converter digital output is

available in 12-bit wide format. The internal registers

are programmed through a 4-wire serial interface for

gain, oﬀset and operating mode adjustments.

• 4-wire serial control interface

• 32-pin QFN package

Applications

• Flatbed document scanners

• Film scanners

• Digital color copiers

• Multifunction peripherals
