TLV986CPFB

Overview

The TLV986CPFB is a monolithic analog signal processor and digitizer designed for area CCD sensor interfacing. It operates from a single 3-V supply with typical power consumption of 140 mW and 2 mW in power-down mode. The device integrates a correlated double sampler (CDS), a programmable gain amplifier (PGA) with 0 to 36 dB range, two internal DACs for offset calibration, and a 10-bit, 12.5 MSPS pipeline ADC. It features a serial interface for register configuration and parallel data output. Available in a 48-pin TQFP package, it is specified over a 0°C to 70°C operating temperature range.

Feature Summary

• Integrates CDS, PGA, and 10-bit ADC for direct CCD sensor processing
• Includes automatic optical black and offset correction via dual DACs
• Supports single 3-V supply operation with low standby power
• Features 3-wire serial interface for internal register control

Applications

• PC Camera
• Digital Still Camera
• Digital Video Camera

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements, specifically the 3-V analog supplies and the 1.8 V to 4.4 V digital interface supply. Confirm that the 48-pin TQFP footprint matches the PCB layout design before finalizing procurement.

Selection Notes

Select this component when interfacing area CCD sensors requiring integrated analog conditioning and high-speed digitization. The device is suitable for applications needing programmable gain adjustment and automatic offset calibration to maximize dynamic range. Consider the 12.5 MSPS conversion rate and 10-bit resolution for bandwidth and precision requirements.

Part Context

The TLV986 is part of Texas Instruments' specialized line of CCD sensor processors. It consolidates multiple discrete analog functions into a single chip to simplify camera system designs. The CPFB variant denotes the commercial temperature range and TQFP packaging, targeting cost-sensitive consumer electronics applications.
