The VSP1221PFBG4 is a mixed-signal integrated circuit designed for signal conditioning and analog-to-digital conversion at the output of CCD arrays. It features a 12-bit, 21-MSPS pipelined ADC, an analog programmable-gain amplifier (PGA), and a digital PGA stage. The device operates from a single 3-V supply with low power consumption of 70 mW and a minimum power-down mode of 4 mW. It includes correlated double sampling (CDS) and optical-black calibration. The component is housed in a 48-pin TQFP package.
Verify that the VSP1221PFBG4 is suitable for your design as it is marked Not Recommended For New Designs (NRND). Confirm the RoHS-compliant lead finish and moisture sensitivity level before ordering. Ensure existing inventory supports production needs as new designs are discouraged by the manufacturer.
Select this component for applications requiring low-power CCD signal processing with high-speed digitization. Consider its 12-bit resolution and 21-MSPS sampling rate against system requirements. Evaluate the need for integrated CDS and optical-black calibration to simplify the external circuit design.
The VSP1221PFBG4 belongs to the VSP1221 series of analog front-end devices manufactured by Texas Instruments. It is specifically engineered for imaging applications involving charge-coupled devices. The 'G4' suffix indicates a lead-free and RoHS-compliant version of the standard VSP1221PFB part.
