ADI squeezes quad DAC into small 3mm x 3mm package

The AD5686, a member of the nanoDAC+™ family is a low power, quad, 16-bit buffered voltage output DAC. The device includes a gain select pin giving a full-scale output of 0V to VREF (gain = 1) or 0V to 2VREF (gain = 2). The device operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP and a TSSOP package.

The AD5686 also incorporates a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remain at that level until a valid write takes place. Each part contains a per-channel power-down feature that reduces the current consumption of the device to 4 µA at 3 V while in power-down mode.

The AD5686 employs a versatile SPI interface that operates at clock rates up to 50 MHz, and all devices contain a VLOGIC pin intended for 1.8 V/3 V/5 V logic.

ADI squeezes quad DAC into small 3mm x 3mm package

Analog Devices has a range of quad 16- and 12-bit 3V/5V digital-to-analogue converters (DACs) in its smallest 3mm x 3mm package.

The AD5686/96 nanoDAC+ quad DACs offer the supplier’s best DC performance specitiofcation. INL is ±2LSB max, offset error is  ±1.5mV max and gain error is ±0.1% max in the LFCSP package with SPI or I²C interface options.

Applications are likely to include PLC (programmable logic controller) I/O cards, digital oscilloscopes, signal generators and optical modules that require low power, rail-to-rail.

The supplier’s AD5316R and AD5317R quad 10-bit nanoDACs offer similar DC performance to the AD5686/96, robustness up to 4kV ESD and low drift on-chip 2.5V voltage reference in a 3mm x 3mm footprint.
