The AD45335 is a 32-channel, 14-bit denseDAC® with an on-chip high voltage output amplifier. This device is targeted for optical micro-electromechanical systems. The output voltage range is programmable via the REF_IN pin. The output range is 0 V to 50 V when REF_IN = 1 V, and 0 V to 200 V when REF_IN = 4 V. REF_IN is buffered internally on the AD45335 and should be driven from a stable reference source.
The selected digital-to-analog converter (DAC) register is written to via the 3-wire interface. The SPI operates at clock rates of up to 30 MHz.
APPLICATIONS
- Optical microelectromechanical systems (MEMS)
- Optical crosspoint switches
- Micropositioning applications using piezoelectric actuators
- Level setting in automotive test and measurement

EVAL-AD45335
Evaluating the AD45335, 32-Channel, 14-Bit, High Voltage Output DAC
Features and Benefits
- Full featured evaluation board for the AD45335
- On-board reference
- PC control in conjunction with the EVAL-SDP-CS1Z or EVALSDP-CB1Z system demonstration platform
- PC software for voltage output control
Product Detail
The EVAL-AD45335SDZ is a full featured evaluation board that can be used to easily evaluate all the features of the EVALAD45335SDZ. The EVAL-AD45335SDZ is a 32-channel, 14-bit, high voltage output denseDAC® with an on-chip high voltage output amplifier.
The AD45335 output voltage range is programmable using the REF_IN pin. The output range is 0 V to 50 V when REF_IN = 1 V, and 0 V to 200 V when REF_IN = 4 V. Each amplifier can source 150 μA. REF_IN is buffered internally on the AD45335 and must be driven from a stable reference source.
The selected digital-to-analog converter (DAC) register is written to using the 3-wire interface. The serial peripheral interface (SPI) operates at clock rates of up to 30 MHz and is compatible with digital signal processing (DSP) and microcontroller interface standards.
The EVAL-SDP-CS1Z or EVAL-SDP-CB1Z board allows the EVALAD45335SDZ to be controlled through the USB port of a PC using the EVAL-AD45335SDZ software.
The EVAL-AD45335SDZ requires 60 V and 5 V external power supplies. On-board components include the REF198, 4.096 V, precision micropower, low dropout, low voltage reference.
