1. general description the adc1015s is a single channel 10-bit a nalog-to-digital converte r (adc) optimized for high dynamic performances and low power consumption at sample rates up to 125 msps. pipelined architecture and output error correction ensure the adc1015s is accurate enough to guarantee zero missing codes over t he entire operating range. supplied from a single 3 v source, it can handle output logic levels from 1.8 v to 3.3 v in cmos mode, because of a separate digital output supply. the adc1015s supports the low voltage differential signalling (lvds) double data rate (ddr) output standard. an integrated serial peripheral interface (spi) allows the user to easily configure the adc. the device also includes a spi programmable full-scale to allow flexible input voltage range from 1 v to 2 v (peak-to-peak). with excellent dynamic performance from the baseband to input frequencies of 170 mhz or more, the adc1015s is ideal for use in communications, imaging and medical applic ations - especially in high intermediate frequency (if) applications because of the integrated input buffer. the input buffer ensures that the input impedance remain s constant and low and the performance consistent over a wide frequency range. 2. features and benefits adc1015s series single 10-bit adc; 65 msps, 80 msps, 105 msps or 125 msps with input buffer; cmos or lvds ddr digital outputs rev. 2 ? 20 december 2010 product data sheet ? snr, 61.7 dbfs / sfdr, 86 dbc ? input bandwidth, 600 mhz ? sample rate up to 125 msps ? power dissipation, 635 mw at 80 msps, including analog input buffer ? 10-bit pipelined adc core ? serial peripheral interface (spi) ? clock input divided by 2 for less jitter contribution ? duty cycle stabilizer ? integrated input buffer ? fast out-of-range (otr) detection ? flexible input voltage range: 1 v (p-p) to 2 v (p-p) ? offset binary, two?s complement, gray code ? cmos or lvds ddr digital outputs ? power-down mode and sleep mode ? pin compatible with the adc1415s series, the adc1215s series and the adc1115s125 ? hvqfn40 package
