The MAX1426 is a 10-bit monolithic analog-to-digital converter (ADC) with a sampling rate of 10Msps. It features an internal track-and-hold (T/H) amplifier for excellent dynamic performance while minimizing external components. The low input capacitance of only 8pF reduces input drive requirements. With a wide input bandwidth of up to 150MHz, this device is suitable for digital RF/IF downconverter applications using undersampling techniques. The MAX1426 utilizes a differential pipelined architecture with a wideband T/H amplifier to maximize throughput while consuming only 156mW of power. It generates an internal +2.5V reference voltage that supplies three additional reference voltages (+3.25V, +2.25V, and +1.25V), providing a differential input range of +2V to -2V. The analog inputs are internally biased to correct the DC level, eliminating the need for external biasing in AC-coupled applications. A separate +3V digital logic supply input allows for the separation of digital and analog circuitry. The output data is in two's complement format. The MAX1426 is available in a space-saving 28-pin SSOP package. For a pin-compatible version with a higher data rate, refer to the MAX1424 or MAX1425.
The Maxim MAX1426 is a 10‑bit, 10 Msps analog‑to‑digital converter featuring an internal track‑and‑hold amplifier, low 8 pF input capacitance and a wide 150 MHz input bandwidth.
The handbook includes absolute maximum ratings, electrical characteristics, pin description, typical operating curves, layout recommendations, package information and revision history for the 28‑pin SSOP device.
