HA17301P
Quad Operational Amplifier
Description
The HA17301P is an internal-compensation quad operational amplifier that operates on a single-voltage
power supply. Typical applications for the HA17301P include waveform generators, voltage regulators,
logic circuits, and voltage-controlled oscillators.
Features
• Wide operating temperature range
• Single-voltage power supply operation
• Internal phase compensation
• Low input bias current

Inverting Amplifier
There are three bias techniques for biasing the inverting amplifier, the single power supply bias technique,
the NVBE bias technique, and the load voltage bias technique.
1. Single Power Supply Bias Technique
Figure 2 shows a common AC amplifier that is biased by the same power supply as the supply that
operates the amplifier.

Figure 3 NVBE Bias Technique
This is the most useful application of an inverting AC amplifier. In this circuit, the input bias voltage
VBE for the inverting input is determined by the current that flows to ground through the resistor R3.
