MAX1426EAI-T
10-Bit, 10Msps ADC
General Description
The MAX1426 10-bit, monolithic analog-to-digital con-
verter (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 downconvert-
er applications employing undersampling techniques.
The MAX1426 employs a differential pipelined architec-
ture with a wideband T/H amplifier to maximize through-
put 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 volt-
ages 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
