Complementary Devices Part No. AD8675 AD8676 ADA4898-1 Description Ultra precision, 36 V, 2.8 nV/√Hz rail-to-rail output op amp Ultra precision, 36 V, 2.8 nV/√Hz dual rail-torail output op amp High voltage, low noise, low distortion, unity gain stable, high speed op amp Table 2. Related Device Part No. AD5781 Description 18-bit, 0.5 LSB INL, voltage output DAC GENERAL DESCRIPTION The AD57911 is a single 20-bit, unbuffered voltage-output DAC that operates from a bipolar supply of up to 33 V. The AD5791 accepts a positive reference input in the range 5 V to VDD − 2.5 V and a negative reference input in the range VSS + 2.5 V to 0 V. The AD5791 offers a relative accuracy specification of ±1 LSB max, and operation is guaranteed monotonic with a ±1 LSB DNL maximum specification. The part uses a versatile 3-wire serial interface that operates at clock rates up to 35 MHz and that is compatible with standard SPI, QSPI™, MICROWIRE™, and DSP interface standards. The part incorporates a power-on reset circuit that ensures the DAC 1 output powers up to 0 V and in a known output impedance state and remains in this state until a valid write to the device takes place. The part provides an output clamp feature that places the output in a defined load state. PRODUCT HIGHLIGHTS 1. 2. 3. 4. 5. 1 ppm Accuracy. Wide Power Supply Range up to ±16.5 V.
