The MAX5865 integrates dual 8-bit receive ADCs and
dual 10-bit transmit DACs while providing ultra-low
power and highest dynamic performance at a conver-
sion rate of 40Msps. The ADCs’ analog input amplifiers
are fully differential and accept 1V
The DACs’ analog outputs are fully differential with
±400mV full-scale output range at 1.4V common mode.
The MAX5865 includes a 3-wire serial interface to con-
trol operating modes and power management. The ser-
ial interface is SPI™ and MICROWIRE™ compatible.
The MAX5865 serial interface selects shutdown, idle,
standby, transmit, receive, and transceiver modes.

The MAX5865 can operate in FDD or TDD applications
by configuring the device for transmit, receive, or trans-
ceiver modes through a 3-wire serial interface. In TDD
mode, the digital bus for receive ADC and transmit
DAC can be shared to reduce the digital I/O to a single
10-bit parallel multiplexed bus. In FDD mode, the
MAX5865 digital I/O can be configured for an 18-bit,
parallel multiplexed bus to match the dual 8-bit ADC
and dual 10-bit DAC.
The MAX5865 features an internal precision 1.024V
bandgap reference that is stable over the entire power-
supply and temperature ranges.
