Rainbow Electronics MAX5661 User Manual
General Description
The MAX5661 single 16-bit DAC with precision highvoltage amplifiers provides a complete solution for programmable current and voltage-output applications.
The output amplifiers swing to industry-standard levels
of ±10V (voltage output) or source from 0mA (or from
4mA) to 20mA (current output). The voltage output
(OUTV) drives resistive loads greater than 2kΩ and
capacitive loads of up to 1.2µF. Voltage-output forcesense connections compensate for series protection
resistors and field-wiring resistance. Short-circuit protection on the voltage output limits output current to
10mA (typ) sourcing or -11.5mA (typ) sinking. The current output (OUTI) drives resistive loads up to 37.5V
(max) and inductive loads up to 1H.
The MAX5661 provides either a current output or a voltage output. Only one output is active at any given time,
regardless of the configuration. The MAX5661 voltage
output operates with ±13.48V to ±15.75V supplies
(V
DDV
, V
SSV
) and the current output operates with a
single +13.48V to +40V supply (V
DDI
). A +4.75V to
+5.25V digital supply (V
CC
) powers the rest of the internal circuitry. A buffered reference input accepts an
external +4.096V reference voltage.
Update the DAC outputs using software commands or
the asynchronous LDAC input. An asynchronous CLR
input sets the DAC outputs to the value stored in the
clear register or to zero. The FAULT output asserts
when the DAC’s current output is an open circuit, the
DAC’s voltage output is a short circuit, or when the CLR
input is low.
The MAX5661 communicates through a 4-wire 10MHz
SPI™-/QSPI™-/MICROWIRE™-compatible serial interface. The DOUT output allows daisy chaining of multiple devices. The MAX5661 is available in a 10mm x
10mm, 64-pin, LQFP package and operates over the
-40°C to +105°C temperature range.
