A nibble more precise then the first DAC click.
If the original 12-bit DAC click was below your requirements, the sequel will be more to your taste. DAC2 click carries LTC2601CDD, which is a 16 bit DAC chip. A single nibble of improvement between 12 and 16 bits brings 61440 more discrete values to convert into a voltage (that's 2^16 - 2^12)
Like its predecesor, this one also uses SPI to fetch the digital values from the host microcontroller. The chip on DAC2 click can do it at a clock rate of up to 50 MHz.
Also, you'll be able to switch between VCC and 4.096V for the reference voltage. The power supply is either 3.3 or 5V.
