PAC27A01
P/ACTIVE PRECISION VOLTAGE DIVIDER NETWORK
Features
Matched resistor pair
Tight parametric control
Long term stability
SOT-23 package for space
critical applications
Product Description
CAMDs PAC27A01 is a precision ratio matched resistor voltage divider network designed to provide tight element-to-
element parametric control and long term stability over time and temperature.
The PAC27A01 supports the Harris HIP5020 Integrated Buck Converter Controller and can also serve other requirements for
precision voltage division.
Applications
Matched resistor pair
Precision division
D/A conversion
Specific Harris HIP5020
support circuit
* For Harris 5020 application (R1=12.4K, R2=20K) only.
Refer to AP-202 Precision Divider Application Note
for further information.
Contact factory for other part marking designations.
