MCP6H91/2/4 NOTES: DS25138B-page 16 2012 Microchip Technology Inc.
MCP6H91/2/4 4.0 APPLICATION INFORMATION The MCP6H91/2/4 family of op amps is manufactured using Microchip’s state-of-the-art CMOS process and is specifically designed for low-power, high-precision applications. 4.1 VDD D1 D2 V1 VOUT Inputs 4.1.1 MCP6H9X V2 PHASE REVERSAL The MCP6H91/2/4 op amps are designed to prevent phase reversal when the input pins exceed the supply voltages. Figure 2-36 shows the input voltage exceeding the supply voltage without any phase reversal. 4.1.
MCP6H91/2/4 4.2 Rail-to-Rail Output 4.3 Capacitive Loads Driving large capacitive loads can cause stability problems for voltage feedback op amps. As the load capacitance increases, the feedback loop’s phase margin decreases and the closed-loop bandwidth is reduced. This produces gain peaking in the frequency response, with overshoot and ringing in the step response. While a unity-gain buffer (G = +1V/V) is the most sensitive to capacitive loads, all gains show the same general behavior.
MCP6H91/2/4 4.6 PCB Surface Leakage 4.7 In applications where low input bias current is critical, PCB surface leakage effects need to be considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low-humidity conditions, a typical resistance between nearby traces is 1012. A 15V difference would cause 15 pA of current to flow; which is greater than the MCP6H91/2/4 family’s bias current at +25°C (10 pA, typical).
MCP6H91/2/4 4.7.2 ACTIVE FULL-WAVE RECTIFIER The MCP6H91/2/4 family of amplifiers can be used in applications such as an active full-wave rectifier, as shown in Figure 4-9. The amplifier and feedback loops in this active voltage rectifier circuit eliminate the diode drop problem that exists in a passive voltage rectifier. This circuit behaves as a voltage follower (the output follows the input) as long as the input signal is more positive than the reference voltage.
MCP6H91/2/4 5.0 DESIGN AIDS Microchip Technology Inc. provides the basic design tools needed for the MCP6H91/2/4 family of op amps. 5.1 SPICE Macro Model The latest SPICE macro model for the MCP6H91/2/4 op amp is available on the Microchip web site at www.microchip.com. The model was written and tested in PSpice, owned by Orcad (Cadence®). For other simulators, translation may be required. The model covers a wide aspect of the op amp’s electrical specifications.
