The ADCDS-1603LC-C is an 16-bit, industry-leading, integrated solution for CCD Signal Processing. This series of analog front-end imaging converters are designed specifically for the very high-resolution imaging applications.

The ADCDS-1603LC-C incorporates a user configurable input amplifier, a low noise correlated double sampler (CDS), and an 16-bit  resolution sampling A/D converter in a single package, providing the user with a complete, high performance, low-cost, low-power, integrated solution. The key to the ADCDS-1603LC-C's performance is a unique, high-speed, high-accuracy CDS circuit, which eliminates the effects of residual charge, charge injection and "kT/C" noise on the CCD's output floating capacitor, producing the pixel’s output signal. The ADCDS-1603LC-C digitizes this resultant pixel signal using a high-speed, low-noise sampling A/D converter.

The ADCDS-1603LC-C features gain adjust, offset adjust, a precision +2.048V reference, a user selectable OVDD supply voltage range of 2.5V, to 3.3V, and a programmable analog bandwidth function. It converts at a maximum speed of 2.3MPPS (Megapixels/Second) and is offered in a small 44-pin SMT plastic package with guaranteed performance over the commercial temperature range of 0 to +70°C .
