General Description

The MAX5661 single 16-bit DAC with precision high-

voltage amplifiers provides a complete solution for pro-

grammable 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 force-

sense connections compensate for series protection

resistors and field-wiring resistance. Short-circuit pro-

tection on the voltage output limits output current to

10mA (typ) sourcing or -11.5mA (typ) sinking. The cur-

rent 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 volt-

age 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

(VDDV, VSSV) and the current output operates with a

single +13.48V to +40V supply (VDDI). A +4.75V to

+5.25V digital supply (VCC) powers the rest of the inter-

nal 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 inter-

face. The DOUT output allows daisy chaining of multi-

ple 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.
