The AD15252 is a dual, 12-bit, 65 MSPS, analog-to-digital converter (ADC) with a differential front-end amplifier, 100 Ω input impedance, 296 mV p-p full-scale input, 170 MHz, 3 dB bandwidth, SNR (-9 dBFS) of 64 dBFS (70 MHz AIN), SFDR (-9 dBFS) of 77 dBFS (70 MHz AIN) and 435 mW / channel power consumption.
The AD15252 is a dual, 12‑bit, 65 MSPS analog‑to‑digital converter optimized for antijam GPS receivers and communications equipment. It features differential front‑end amplification, 100 Ω input impedance, and a full‑scale differential input range of 296 mV p‑p. Data is output on two parallel 12‑bit buses in either straight binary or two's‑complement format.
The device operates from a single 3.3 V analog supply (AVDD) with a separate 2.5 V/3.3 V digital output driver supply (DRVDD). It is packaged in an 8 mm × 8 mm CSP‑BGA and is rated for the industrial temperature range of –40 °C to +85 °C. Typical performance includes 64 dBFS SNR and 77 dBFS SFDR at 70 MHz input.
