Full Accurate 3 V/5 V 14-Bit VOUT nanoDAC® Converter, Output Buffered, in a Sot 23

Manufactured by:

Product Details

The AD5040, a member of the nanoDAC® family, is a single full accurate 14-bit buffered voltage out DAC in a SOT-23  

By combining a 14-bit DAC and high performance output buffer in a SOT-23, the AD5040 delivers a maximum 1 LSB INL linearity error, making it ideal for high performance applications such as open loop control or precision gain and offset. The part utilizes a versatile three-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI™, QSPI™, MICROWIRE™ and DSP interface standards. The reference for the AD5040 is supplied from an external REF pin with a reference buffer provided on chip to simplify application of the device. The part incorporates a power-on-reset circuit that ensures the DAC output powers up to zero volts and remains there until a valid write takes place to the device. The part also contains a power-down feature that reduces the current consumption of the device to 1 µA at 5 V and provides software selectable output loads while in power-down mode. Power-down mode is activated over the serial interface with very low glitch on power up.

Product Details

The evaluation board helps users quickly prototype new circuits for the AD5040/AD5060, AD5061, or AD5062 and reduce design time. The AD5040/AD5060, AD5061, and AD5062 operate from a single 2.7 V to 5.5 V supply. An ADR444 is provided on-board as a 4.096 V reference source.

Full data on the AD5040/AD5060, AD5061, and AD5062 is available in the appropriate data sheet, which should be consulted in conjunction with user guide UG-923 when using the evaluation board.

The evaluation board interfaces to the USB port of a PC via the SDP board. Software is supplied with the evaluation board to allow the user to program the AD5040/AD5060, AD5061, or the AD5062.

The evaluation boards are compatible with the EVAL-SDP-CB1Z Blackfin® SDP controller board (SDP-B).
