Pin Description
Pin Configuration
Detailed Description
The MAX5214/MAX5216 are pin-compatible and soft-
ware-compatible 14-bit and 16-bit DACs. The MAX5214/
MAX5216 are single-channel, low-power, high-refer-
ence input resistance, and buffered voltage-output
DACs. The MAX5214/MAX5216 minimize the digital
noise feedthrough from their inputs to their outputs by
powering down the SCLK and DIN input buffers after
completion of each data frame. The data frames are
16-bit for the MAX5214 and 24-bit for the MAX5216. On
power-up, the MAX5214/MAX5216 reset the DAC output
to zero, providing additional safety for applications that
drive valves or other transducers which need to be off on
power-up. The MAX5214/MAX5216 contain a segmented
resistor string-type DAC, a serial-in/parallel-out shift reg-
ister, a DAC register, power-on-reset (POR) circuit, CLR
to asynchronously clear the device independent of the
serial interface, and control logic. On the falling edge
of the clock (SCLK) pulse, the serial input (DIN) data is
shifted into the device, MSB first.
Output Amplifier (OUT)
The MAX5214/MAX5216 include an internal buffer on the
DAC output. The internal buffer provides improved load
regulation and transition glitch suppression for the DAC
output. The output buffer slews at 0.5V/Fs and drives
up to 10kI in parallel with 100pF. The analog supply
voltage (VDD) determines the maximum output voltage
range of the device as VDD powers the output buffer.
DAC Reference (REF)
The external reference input features a typical input
impedance of 256kI and accepts an input voltage
from +2V to VDD. Connect an external voltage supply
between REF and GND to apply an external reference.
