Product Details

The LTC2185IUP is A two-channel simultaneous sampling 16-bit A/D converter, specifically designed for digital processing of high-frequency and wide dynamic range signals. The LTC2185IUP is highly suitable for demanding communication applications, with its AC performance including 76.8dB SNR and 90dB parasitic dynamic range (SFDR). The ultra-low jitter of 0.07psRMS achieves undersampling at the IF frequency and excellent noise performance.

The DC specification includes ±2LSB INL (typical value), ±0.5LSB DNL (typical value) and no missed codes throughout the entire temperature range. Convert the noise to 3.4LSBRMS.

The digital output can be full-rate CMOS, double data rate CMOS or double data rate LVDS. A separate output power supply provides a CMOS output swing ranging from 1.2V to 1.8V.

Differential or single-ended driving of ENC+ and ENC - inputs can be performed using a sine wave, PECL, LVDS, TTL or CMOS input. An optional clock duty cycle stabilizer achieves high performance under full-speed and multiple clock duty cycle conditions.

Application field

The LTC2185IUP is applicable to the following fields:
