Description

The LTC®2203/LTC2202 are 25Msps/10Msps, sampling 16-bit A/D converters designed for digitizing high frequency, wide dynamic range signals up to input frequencies of 400MHz. The input range of the ADC can be optimized with the PGA front end.

The LTC2203/LTC2202 are perfect for demanding applications, with AC performance that includes 81.4dB SNR and 100dB spurious free dynamic range (SFDR). Maximum DC specs include ±4LSB INL, ±1LSB DNL (no missing codes) over temperature

A separate output power supply of LTC2204 allows the CMOS output swing to range from 0.5V to 3.3V.

A single-ended CLK input controls converter operation. An optional clock duty cycle stabilizer allows high performance at full speed with a wide range of clock duty cycle.
