Eight channels, 12 bits, one supply rail
The MAX5306EUE+ is an 8-channel, 12-bit voltage-output DAC from Analog Devices in a 16-TSSOP package. Each of the eight converters drives a buffered output, so the DAC output can source or sink current without an external op-amp on each channel.
Settling time and interface speed
Typical settling time is 5 µs to 0.5 LSB. For an 8-channel system updating all channels sequentially, the per-channel update rate is roughly 200 kHz before the settling window limits throughput. The SPI/DSP interface accepts clock rates well above that, so the bus speed is not the bottleneck — the DAC's own settling is. The INL and DNL are both ±1 LSB max. At 12-bit resolution on a 2.5 V reference, 1 LSB is about 610 µV. A ±1 LSB DNL guarantees no missing codes across all eight channels, which matters when the DAC drives a closed-loop trim or a calibration DAC that must hit every step.
