AD737ANZ - Brand New Analog Devices RMS-to-DC Converters
-
Description
The AD737ANZ is a low power, precision, monolithic, true rms-to dc converter. It is laser trimmed to provide a maximum error of ±0.2 mV ± 0.3% of reading with sine wave inputs. With its small physical size and low cost, this converter is suitable for upgrading the performance of non-rms precision rectifiers in various applications. Compared to other circuits, the AD737ANZ offers higher accuracy at an equal or lower cost.
Specifications and features
- Computes True rms value
- Computes Average rectified value
- Computes Absolute value
- Provides 200 mV full-scale input range (larger inputs with input scaling)
- Direct interfacing with 3½ digit CMOS ADCs
- High input impedance: 1012 Ω
- Low input bias current: 25 pA maximum
- High accuracy: ±0.2 mV ± 0.3% of reading
- RMS conversion with signal crest factors up to 5
- Wide power supply range: ±2.5 V to ±16.5 V
- Low power: 25 µA (typical) standby current
- No external trims needed for specified accuracy
- The AD737ANZ output is negative-going; the AD736 is a positive output-going version of the same basic device
Application Scenarios
The AD737ANZ can be used in various applications that require precision and accurate rms-to-dc conversion. It can be particularly useful in upgrading the performance of non-rms precision rectifiers.
Comparison
