DIGITAL-TO-ANALOG CONVERTER with 2.5V, 2ppm/В°C Internal Reference
Check for Samples: DAC7564 FEATURES DESCRIPTION Relative Accuracy: 0.5LSB Glitch Energy: 0.15nV-s Internal Reference:
– 2.5V Reference Voltage (enabled by default)
– 0.004% Initial Accuracy (typ)
– 2ppm/°C Temperature Drift (typ)
– 5ppm/°C Temperature Drift (max)
– 20mA Sink/Source Capability Power-On Reset to Zero-Scale Ultra-Low Power Operation: 1mA at 5V Wide Power-Supply Range: +2.7V to +5.5V 12-Bit Monotonic Over Temperature Range Settling Time: 10μs to ±0.024% Full-Scale
Range (FSR) Low-Power Serial Interface with
Schmitt-Triggered Inputs: Up to 50MHz On-Chip Output Buffer Amplifier with
Rail-to-Rail Operation 1.8V to 5.5V Logic Compatibility Temperature Range: –40°C to +105°C The DAC7564 is a low-power, voltage-output,
four-channel, 12-bit digital-to-analog converter (DAC).
The device includes a 2.5V, 2ppm/В°C internal
reference (enabled by default), giving a full-scale
output voltage range of 2.5V. The internal reference
has an initial accuracy of 0.02% and can source up to
20mA at the VREFH/VREFOUT pin. The device is
monotonic, provides very good linearity, and
minimizes undesired code-to-code transient voltages
(glitch). The DAC7564 uses a versatile 3-wire serial
interface that operates at clock rates up to 50MHz.
The interface is compatible with standard SPIв„ў, …
