The LTC2192/LTC2191/LTC2190 are 2-channel, simultaneous sampling 16-bit A/D converters designed for digitizing high frequency, wide dynamic range signals. They are perfect for demanding communications applications with AC performance that includes 77dB SNR and 90dB spurious free dynamic range (SFDR). Ultralow jitter of 0.07psRMS allows undersampling of IF frequencies with excellent noise performance.

DC specs include ±2LSB INL (typ), ±0.5LSB DNL (typ) and no missing codes over temperature. The transition noise is 3.3LSBRMS.

To minimize the number of data lines the digital outputs are serial LVDS. Each channel outputs one bit, two bits or four bits at a time. The LVDS drivers have optional internal termination and adjustable output levels to ensure clean signal integrity.

The ENC+ and ENC inputs may be driven differentially or single ended with a sine wave, PECL, LVDS, TTL or CMOS inputs. An internal clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
