Detailed Description
The MAX5312 12-bit DAC operates from either single or
dual supplies. Dual ±12V to ±15V power supplies pro-
vide a bipolar ±5V to ±10V output, or a unipolar 0 to 10V
output. Single 12V to 15V power supplies provide only a
unipolar 0 to 10V output. The reference input accepts
voltages from 2V to 5.25V. The DAC features INL and
DNL less than ±1 LSB (max), a fast 10s settling time,
and a hardware-shutdown mode that reduces current
consumption to 3.5A (max). The device features a
10MHz SPI-/QSPI-/MICROWIRE-compatible serial inter-
face that operates with 3V or 5V logic, an asynchronous
load input, and a serial-data output. The device offers a
CLR that sets the DAC output to 0V. Figure 1 shows the
functional diagram of the MAX5312.
Serial Interface
An SPI-/QSPI-/MICROWIRE-compatible serial interface
allows complete control of the DAC through a 16-bit
control word. The first 4 bits form the control bits that
determine register loading and software-shutdown
functions. The last 12 bits form the DAC data. The 16-
bit word is entered MSB first.
Table 1 shows the serial-data format. Table 2 shows
the interface commands.
The MAX5312 can be programmed while in shutdown.
The serial interface contains three registers: a 16-bit shift
register, a 12-bit input register, and a 12-bit DAC register
(Figure 1). The shift register accepts data from the serial
interface. The input register acts as a holding register for
data going to the DAC register and isolates the shift reg-
ister from the DAC register. The DAC register controls
the DAC ladder and thus the output voltage. Any update
in the DAC register updates the output voltage.
