Part Number: DAC7612
Other Parts Discussed in Thread: DAC53202, DAC53701, DAC63204, DAC63202

Tool/software:

could you help recommend the most commonly used DAC IC

8~12bit, SPI, I2C, PWM control interface level Output can reach 10V or above,

dual CH is preferred, single CH is also acceptable

Hi Gareth,

We do not really have any PWM output devices, but our smart DAC devices can generate a PWM with some special configuration. These are limited to ~5V operation. Consider the DAC53202 or the DAC53701.

Hi Paul

Thanks for your reply

The customer is not looking for PWM output, the output is ANALOG PWM is the input control signal

The input control signal can be i2c, spi or pwm

Hi Gareth,

DAC63204 (for dual channel) in the following configuration would be a way to get an I2C/SPI to variable duty cycle PWM output:

Or DA53701 (for single channel) or DAC63202 (for dual channel) in the following configuration is a way to get an analog input to variable duty cycle PWM output:

These are the only DAC options we have for PWM generation.

Best,

Katlynne Jones
