Bias Generation and Level Setting Made Easy with Multiple Range, User Programmable Voltage Output D/A Converter

Business Wire
Analog Devices, Inc. (NASDAQ: ADI) today introduced a
single-chip, universal output D/A converter which combines a 16-bit
data converter, ±2 ppm/°C 2.5-V reference, output buffer and gain
scaling function on-chip. The innovative feature set of the AD5761R
converter removes the need for external components, including gain
setting precision resisters and amplifiers. In data acquisition and
actuator control applications, this quickens and simplifies system
design, enabling both unipolar and bipolar operation, through a
software register update. Without affecting system design effort,
cost or size, the new, flexible D/A converter facilitates design
reuse across multi-functional end-equipment, while also enabling
enhanced system functionality through the multiple output voltage
ranges. Additionally, ADI announced two dual DC-DC regulators that
power the new D/A converter with two independently regulated
positive and negative rails for power sensitive applications. This
simple two-chip solution enables users to generate bipolar 10-V
outputs from only a single, low-voltage positive supply rail, which
greatly simplifies system design and removes the need for routing
multiple high-voltage rails.

Offering a 60 percent space savings over previous discrete
solutions, the AD5761R’s single-chip 3-mm × 3-mm LFCSP standard
package is ideal for designs within shrinking form factors, such as
actuator control. The total unadjusted error specification — ±
0.15% FSR max — is a true error including all on-chip circuitry and
reference. This enables more accurate end systems and eliminates
multiple system calibration routines in industrial
environments. For a lower cost, less accurate option within
the same series, a pin compatible 12-bit version and non-reference
options are also available.
AD5761R Key Specifications:
- 8 software-programmable output ranges
with 5% over-range: 0 V to 5 V, 0 V to 10 V, 0 V to 16 V, 0 V to 20
V, ±3 V, ±5 V, ±10 V, and −2.5 V to +7.5 V
- Robust feature set including
diagnostic, temperature, brownout and short circuit alert
