说明

The MAX1426 10-bit, monolithic analog-to-digital converter (ADC) is capable of a 10Msps sampling rate. This device features an internal track-and-hold (T/H) amplifier for excellent dynamic performance; at the same time, it minimizes the number of external components. Low input capacitance of only 8pF minimizes input drive requirements. A wide input bandwidth (up to 150MHz) makes this device suitable for digital RF/IF downconverter applications employing undersampling techniques.

The MAX1426 employs a differential pipelined architecture with a wideband T/H amplifier to maximize throughput while limiting power consumption to only 156mW. The MAX1426 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 MAX1426 is available in the space-saving 28-pin SSOP package. For a pin-compatible version at a higher data rate, refer to the MAX1424 or MAX1425.
