61.6dB SNR, 85dB SFDR
with AC performance that includes 61.6dB SNR and 85dB ■ 110dB Channel Isolation at 100MHz SFDR for signals at the Nyquist frequency. ■ Flexible Input: 1VP-P to 2VP-P Range DC specs include ±0.1LSB INL (typ), ±0.1LSB DNL (typ) ■ 575MHz Full Power Bandwidth S/H and ±0.6LSB INL, ±0.6LSB DNL over temperature. The ■ Clock Duty Cycle Stabilizer transition noise is a low 0.08LSB ■ Shutdown and Nap Modes RMS. ■ Pin Compatible Family A single 3V supply allows low power operation. A separate 105Msps: LTC2282 (12-Bit), LTC2280 (10-Bit) output supply allows the outputs to drive 0.5V to 3.6V 80Msps: LTC2294 (12-Bit), LTC2289 (10-Bit) logic. 65Msps: LTC2293 (12-Bit), LTC2288 (10-Bit) A single-ended CLK input controls converter operation. An 40Msps: LTC2292 (12-Bit), LTC2287 (10-Bit) optional clock duty cycle stabilizer allows high perfor- 25Msps: LTC2291 (12-Bit), LTC2286 (10-Bit) mance at full speed for a wide range of clock duty cycles. 10Msps: LTC2290 (12-Bit) , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
