AVAGO 隔离放大器HCPL-7800-000E

AVAGO 隔离放大器HCPL-7800-000E

隔离放大器是一种特殊的测量放大电路，其输入、输出和电源电路之间没有直接电路耦合，即信号在传输过程中没有公共的接地端。输入电路和放大器输出之间有欧姆隔离的器件。

applications.

The product can also be used for general analog signal

isolation applications requiring high accuracy, stability,

and linearity under similarly severe noise con-ditions.

For general applications, we recommend the HCPL-7800

(gain tolerance of ±3%). For precision applications Avago

Technologies offers the HCPL-7800A with part-to-part

gain tolerance of ±1%. The HCPL-7800(A) utilizes sigma

delta (Σ−∆) analog-to-digital converter technology,

chopper stabilized amplifiers, and a fully differential

circuit topology.

Together, these features deliver unequaled isolationmode noise rejection, as well as excellent offset and

gain accuracy and stability over time and temperature.

This performance is delivered in a compact, auto-insertable, industry standard 8-pin DIP package that meets

worldwide regulatory safety standards. (A gull-wing

surface mount option #300 is also available).
