14-bit DAC with I²C bus and single-supply simplicity
The MAX5215GUA+ is a single-channel 14-bit digital-to-analog converter from Analog Devices with a buffered voltage output and an R-2R ladder architecture. It communicates over an I²C serial interface, which keeps the pin count low on the 8-uMAX package. The operating temperature range spans -40°C to 105°C, covering industrial and extended-commercial environments.
Settling time and output drive
Typical settling time is 18 µs to 0.5 LSB for a full-scale step. This sets the maximum update rate the DAC can sustain without sacrificing accuracy — useful for closed-loop control loops or waveform generation below roughly 55 kHz. The voltage output is buffered, meaning the DAC can drive a resistive or capacitive load directly without an external op-amp. The output is single-ended with no differential output option. INL is specified at ±0.4 LSB and DNL at ±0.1 LSB, both typical. The DNL figure below ±0.5 LSB guarantees monotonicity across the full 14-bit range — no missing codes.
Package, footprint, and compliance
The device is offered in an 8-uMAX package (8-TSSOP / 8-MSOP, 3.00 mm width) and is supplied in a Tube. Mounting is surface-mount, so the board footprint matches the standard MSOP-8 land pattern. The reference type is external — the DAC output accuracy depends on the reference voltage applied to the REF pin. No internal reference is provided.
