The MAX1425 employs a differential pipelined architecture with a wideband T/H amplifier to maximize throughput while limiting power consumption to only 172mW. The MAX1425 generates an internal +2.5V reference that supplies three additional reference voltages (+3.25V, +2.25V, and +1.25V). These reference voltages provide a differential input range of +2V to -2V. The analog inputs are biased internally to correct the DC level, eliminating the need for external biasing on AC-coupled applications.
A separate +3V digital logic supply input allows for separation of digital and analog circuitry. The output data is in two's complement format. The MAX1425 is available in the space-saving 28-pin SSOP package. For a pin-compatible version at a lower data rate, refer to the MAX1426 data sheet. For a higher data rate, refer to the MAX1424 data sheet.
