Image and Text Details

The HJG830 is a high-speed, precision differential amplifier fabricated using a thick-film integrated process compliant with GJB2438B. It comprises a precision resistor network and a precision operational amplifier; the resistors are laser‑trimmed to achieve accurate gain and superior common-mode rejection. With enhanced integration and reliability, it is suitable for high-speed signal processing and video applications. The HJG830A operates from a single supply and, built on the foundation of a precision differential amplifier, incorporates an internal reference circuit, eliminating the need for an external bias signal and ensuring the output remains continuously at 1/2 VCC. The HJG830B is powered by a dual supply, with the output biased to ground. The HJG830C also uses a single supply but features an external reference, allowing the output to be adjusted. The HJG830 is a fully domestically produced product that can functionally replace the AD830.
The main features are:
Built-in gain setting
Output bias: 1/2 VCC (A), GND (B), C (VCM)
Supply voltage: 5.5 V to 18 V
Ultra-high slew rate of 240 V/μs
Offset voltage 2.5 mV
-3 dB bandwidth: 40 MHz
