AD9269BCPZ-20

AD9269 is a monolithic, dual-channel, 16bit, 20MSPS analog-to-digital converter (ADC). It features a high performance sample-and-hold circuit and on-chip voltage reference. The AD9269 incorporates an optional integrated DC correction and quadrature error correction block (QEC) that corrects for DC offset, gain, and phase mismatch between the two channels. This functional block can be very beneficial to complex signal processing applications such as direct conversion receivers. The ADC also contains several features designed to maximize flexibility and minimize system cost, such as programmable clock and data alignment and programmable digital test pattern generation. Typical applications include communications, multimode digital receivers (3G) (GSM, EDGE, W-CDMA, LTE, CDMA2000, WiMAX and TD-SCDMA), I/Q demodulation systems, smart antenna systems, battery-powered instruments, handheld scope meters, portable medical imaging, ultrasound, radar/LIDAR.
