Description

The Microchip Technology Inc. MCP6051/2/4 family of

operational amplifiers (op amps) has low input offset

voltage (

±150 µV, maximum) and rail-to-rail input and

output operation. This family is unity gain stable and

has a gain bandwidth product of 385 kHz (typical).

These devices operate with a single supply voltage as

low as 1.8V, while drawing low quiescent current per

amplifier (30 µA, typical). These features make the

family of op amps well suited for single-supply, high

precision, battery-powered applications.

The MCP6051/2/4 family is offered in single

(MCP6051), dual (MCP6052), and quad (MCP6054)

configurations.

The MCP6051/2/4 is designed with Microchip’s

advanced CMOS process. All devices are available in

the extended temperature range, with a power supply

range of 1.8V to 6.0V.

MCP6051/2/4 4.0 APPLICATION INFORMATION The MCP6051/2/4 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 D1 U1 D2 V1 MCP605X Rail-to-Rail Input 4.1.1 VDD VOUT V2 PHASE REVERSAL The MCP6051/2/4 op amps are designed to prevent phase reversal when the input pins exceed the supply voltages. Figure 2-34 shows the input voltage exceeding the supply voltage without any phase reversal.
PAGE 16
MCP6051/2/4 4.2 Rail-to-Rail Output The output voltage range of the MCP6051/2/4 op amps is VSS + 15 mV (minimum) and VDD – 15 mV (maximum) when RL = 10 kΩ is connected to VDD/2 and VDD = 6.0V. Refer to Figures 2-27 and 2-28 for more information. 4.3 4.4 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.
PAGE 17
MCP6051/2/4 4.6 PCB Surface Leakage 4.7 In applications where low input bias current is critical, Printed Circuit Board (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 1012Ω. A 5V difference would cause 5 pA of current to flow; which is greater than the MCP6051/2/4 family’s bias current at +25°C (±1.0 pA, typical).
PAGE 18
MCP6051/2/4 4.7.2 INSTRUMENTATION AMPLIFIER The MCP6051/2/4 op amps are well suited for conditioning sensor signals in battery-powered applications. Figure 4-9 shows a two op amp instrumentation amplifier, using the MCP6052, that works well for applications requiring rejection of common mode noise at higher gains. The reference voltage (VREF) is supplied by a low impedance source. In single supply applications, VREF is typically VDD/2.
