MCP607-I/ST - Dual 155kHz CMOS Op Amp | Microchip
Teilenummer: MCP607-I/ST ✓ AktivMCP607-I/ST Übersicht
An operational amplifier is a voltage-gain building block used to amplify small signals, buffer sensors, drive analog stages, and implement active filters. The MCP607 belongs to the micropower CMOS operational-amplifier hierarchy, combining low bias current, low quiescent consumption, rail-to-rail output capability, and unity-gain stability. These characteristics make it suitable for battery-powered equipment, portable instrumentation, low-power audio paths, and general analog signal-conditioning systems.
Principal features include a 155 kHz gain-bandwidth product, a maximum input offset voltage of 250 uV, a typical operating current of 18.7 uA, and a maximum quiescent current of 25 uA. The device also provides 91 dB common-mode rejection and an 0.0800 V/uS slew rate. Its CMOS input stage supports input bias current as low as 80 pA at +85 degrees C, helping preserve accuracy when sensing high-impedance sources.
The dual configuration contains two independent amplifiers within one package, reducing board area compared with two separate single-channel devices. Both channels are unity-gain stable and use rail-to-rail output stages, allowing the output to approach the supply limits under suitable load conditions. Single-supply operation simplifies portable-system design because the signal can be biased around ground or a midpoint reference without a negative rail.
Typical applications include low-power sensor conditioning, portable audio amplification, battery-operated test equipment, analog-to-digital converter input buffers, and general voltage buffering. In a high-impedance sensor interface, the low input bias current limits error generated by the source resistance. In a low-frequency filter or gain stage, the 155 kHz bandwidth provides useful bandwidth while the 18.7 uA typical operating current limits power consumption.
Designers should review the MCP607 input common-mode range, output-load limits, stability behavior, and noise characteristics against the intended signal path. Input and output filtering, grounding, and decoupling should follow the recommended application circuit in the manufacturer datasheet, especially when the amplifier drives capacitive loads or operates near its supply-voltage limits.
This page combines the manufacturer device characteristics with practical application guidance, a parameter comparison, package details, and engineering-oriented design notes. It helps engineers evaluate the MCP607-I/ST for low-power analog systems without obscuring the differences between operation current, bandwidth, offset voltage, and temperature grade.

Typische Anwendungen
MCP607-I/ST ist geeignet für 6 Anwendungs: Battery-Powered Sensor Conditioning, Portable Audio Signal Conditioning, Low-Power ADC Input Buffer, Precision Voltage Buffer, Low-Frequency Active Filter, Industrial Measurement Interface.
Battery-Powered Sensor Conditioning
The MCP607-I/ST fits low-power sensor interfaces because its 18.7 uA typical operating current and 80 pA maximum input bias current at +85 degrees C reduce errors from high source resistance. The two unity-gain-stable channels can provide one stage of gain and the other can buffer the sensor before an ADC. Operate from a 2.5 V to 6.0 V single supply and place the amplifier close to the sensor return to minimize noise pickup. Its below-250 uV offset rating supports precision conditioning, although the complete error budget should include sensor drift, resistor tolerance, and ADC input characteristics.
Empfohlen
Portable Audio Signal Conditioning
The MCP607-I/ST is useful for pre-amplifier and buffering stages in portable audio equipment because it combines rail-to-rail output swing with a 155 kHz gain-bandwidth product and 18.7 uA typical operating current. Its 91 dB common-mode rejection helps reject common-mode interference in a compact analog path. The 8-pin TSSOP package saves board area, while the dual configuration can condition left and right channels. Designers should verify the required output amplitude, load impedance, and headroom before using the amplifier to drive headphones or another low-impedance stage.
Empfohlen
Low-Power ADC Input Buffer
The MCP607-I/ST can buffer a sensor or divider network into an analog-to-digital converter without drawing the substantial current associated with a general-purpose precision amplifier. Its 155 kHz gain-bandwidth product accommodates low-frequency acquisition signals, while the maximum input offset voltage below 250 uV helps control DC error. Both channels are unity-gain stable, allowing one to drive an ADC input and the other to support gain or reference conditioning. Confirm ADC input capacitance and the MCP607 output stability behavior when driving long capacitive traces or an acquisition network.
Empfohlen
Precision Voltage Buffer
The MCP607-I/ST works as a voltage buffer when high input impedance and low output loading are more important than high bandwidth. Its low bias current of 80 pA maximum at +85 degrees C minimizes disturbance to a high-impedance source, while the 18.7 uA typical operating current supports portable instruments. The rail-to-rail output allows useful signal range on a single 2.5 V to 6.0 V supply. For potentiometer, bridge, or divider interfaces, include suitable filtering and verify the input common-mode range at the selected supply voltage and operating temperature.
Empfohlen
Low-Frequency Active Filter
The MCP607-I/ST is suitable for first-order or modest-bandwidth active-filter stages where low quiescent current is valuable. A 155 kHz gain-bandwidth product provides ample loop gain for many low-frequency filter designs, and unity-gain stability supports direct buffer configurations. Its 0.0800 V/uS slew rate should be checked against the filter output waveform and frequency. Use stable resistor and capacitor selections, keep the two amplifier channels electrically independent, and follow the manufacturer’s recommended application circuit when noise, loading, or dynamic-range behavior is critical.
Empfohlen
Industrial Measurement Interface
The MCP607-I/ST can condition slow industrial measurement signals while operating from a 2.5 V to 6.0 V rail. Its -40 degrees C to +85 degrees C operating range, 91 dB common-mode rejection, and low typical operating current of 18.7 uA support compact acquisition electronics. The dual package provides separate channels for a measurement signal and an excitation or reference path. Protection against industrial transients should be implemented outside the amplifier, and the input common-mode and output ranges must remain within the manufacturer limits over the complete temperature range.

Designhinweise
Budget the MCP607-I/ST supply current from the manufacturer’s 18.7 uA typical operating-current figure while including both channels, load current, and upstream regulator tolerance. Because the device accepts 2.5 V to 6.0 V, check whether a low quiescent-current rail creates an output-voltage margin problem at light load. Use local bypass capacitance and a low-impedance ground return so switching ripple from the supply does not become input-referred noise in the amplifier.
Do not assume that rail-to-rail output swing guarantees an exact zero-volt or full-supply output under every load. Check the manufacturer’s output-voltage headroom curves against the required load current and temperature. Likewise, verify the input common-mode range for the selected supply voltage. The MCP607-I/ST is unity-gain stable, but driving a capacitive load directly can still require an isolation resistor or additional compensation.
Place the device close to the source being buffered to minimize capacitive loading and noise pickup on a high-impedance input. Keep the ground return short and route both amplifier channels with short, symmetrical signal paths. Place supply bypass capacitance near the device pins and keep high-current return currents out of the sensitive input-reference trace. Review the TSSOP land pattern against the official package drawing before PCB release.
For sensor and high-impedance inputs, minimize leakage around the input pins and use guarding where practical. The 80 pA maximum bias current at +85 degrees C is low, but board contamination and connector leakage can still create meaningful errors at very high source impedances. Add input filtering with capacitors whose leakage and dielectric behavior suit the signal bandwidth, and avoid routing the input across long supply or switching-regulator regions.
