GENERAL DESCRIPTION
The AD5541/AD5542 are single, 16-bit, serial input, voltage
output DACs. They operate from a single supply ranging from
2.7 V to 5 V and consume typically 300 mA with a supply of
5 V. Data is written to these devices in a 16-bit word format, via
a 3- or 4-wire serial interface. To ensure a known power-up state,
these parts were designed with a power-on reset function. In uni-
polar mode, the output is reset to 0 V, while in bipolar mode, the
AD5542 output is set to –V
REF
. Kelvin sense connections for
the reference and analog ground are included on the AD5542.
Digital-to-Analog Section
The DAC architecture consists of two matched DAC sections.
A simplified circuit diagram is shown in Figure 18. The DAC
architecture of the AD5541/AD5542 is segmented. The four
MSBs of the 16-bit data word are decoded to drive 15 switches,
E1 to E15. Each of these switches connects one of 15 matched
resistors to either AGND or V
REF
. The remaining 12 bits of the
data word drive switches S0 to S11 of a 12-bit voltage mode
R-2R ladder network.

With this type of DAC configuration, the output impedance
is independent of code, while the input impedance seen by
the reference is heavily code dependent. The output voltage
is dependent on the reference voltage as shown in the follow-
ing equation.

Serial Interface
The AD5541 and AD5542 are controlled by a versatile 3-wire
serial interface, which operates at clock rates up to 25 MHz and
is compatible with SPI, QSPI, MICROWIRE, and DSP interface
standards. The timing diagram can be seen in Figure 1. Input
data is framed by the chip select input,
CS
. After a high-to-low
transition on
CS
, data is shifted synchronously and latched into
the input register on the rising edge of the serial clock, SCLK.
Data is loaded MSB first in 16-bit words. After 16 data bits
have been loaded into the serial input register, a low-to-high
transition on
CS
transfers the contents of the shift register to the
DAC. Data can only be loaded to the part while
CS
is low.
