AD5790BCPZ-RL7

系统就绪， 20位， ± 2LSB INL System Ready, 20-Bit, ±2LSB INL

Product Details

The AD5790 1 is a single 20-bit, voltage out Dac that operates from a bipolar supply up to 33V. Reference buffers are also provided on-chip The AD5790 accepts a positive reference input in the range of 5V to VDD – 2.5V and a negative reference input in the range of VSS + 2.5v to 0V. The AD5790 offers a relative accuracy of +/-2 LSB"s max and operation is guaranteed monotonic with a -1 LSB to +3 LSB"s DNL specification.

The part uses a versatile 3-wire serial interface that operates at clock rates up to 35 MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0V and in a known output impedance state and remains in this state until a valid write to the device takes place. The part provides a disable feature that places the output in a defined load state.
