DAC7811: device selection for Time Gain Control (SLAA724)

AnBer

Part Number: DAC7811

Team,

I am trying to find a DAC (with serial interface and low noise) that meets the specs from section 5 of "Time Gain Control (Compensation) in Ultrasound Applications - SLAA724":
http://www.ti.com/lit/an/slaa724/slaa724.pdf

With those parameters the DAC list given by the web selection would be:
http://www.ti.com/data-converters/dac-circuit/precision/products.html#p84=8;12&p1021=1;2&p158=I2C;SPI;UART;Single-Wire&p112=0.1;1&p596=1;10

Are there some other recommendation that I would have missed?

Thanks in advance,

Anthony,

For the most part I think those two devices are going to be your best bets assuming you need 12-bits of resolution.

Would there be some alternative for 10 bits?

Hello Anthony,

The relevant devices given the settling time and other requirements would be either 8-bit or 12-bit.
