GENERAL DESCRIPTION
The AD57601 is a true 16-bit, unbuffered voltage output DAC
that operates from a bipolar supply of up to 33 V. The AD5760
accepts a positive reference input range of 5 V to VDD − 2.5 V
and a negative reference input range of VSS + 2.5 V to 0 V. The
AD5760 offers a relative accuracy specification of 0.5 ꢀSB
maximum range, and operation is guaranteed monotonic with a
0.5 ꢀSB DNꢀ maximum range specification.
PRODUCT HIGHLIGHTS
1. True 16-bit accuracy.
2. Wide power supply range of up to 16.5 V.
3. −40°C to +125°C operating temperature range.
4. ꢀow 8 nV/√Hz noise.
5. ꢀow 0.018 ppm/°C gain error temperature coefficient.
COMPANION PRODUCTS
The part uses a versatile 3-wire serial interface that operates at
clock rates of 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 that the
DAC output powers up to 0 V 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.
Output Amplifier Buffer: AD8675, ADA4898-1, ADA4004-1
External Reference: ADR445
DC-to-DC Design Tool: ADIsimPower™
