Product details
Overview
MCP6292IDR from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for low-power, wide-supply general-purpose applications. It delivers 10-MHz gain bandwidth, 600-μA per amplifier quiescent current, and 8.7 nV/√Hz input voltage noise at 10 kHz - enabling precision signal conditioning in battery-powered sensor interfaces and analog front-ends.
For engineers reviewing the MCP6292IDR datasheet, MCP6292IDR pinout, MCP6292IDR application, or MCP6292IDR equivalent, key selection criteria include its extended temperature range (–40°C to 125°C), unity-gain stability with capacitive loads up to 300 pF, resistive open-loop output impedance for improved stability, and integrated RFI/EMI filtering for noisy environments.
Technical Context
The MCP6292IDR employs a complementary differential input stage (N-channel + P-channel pairs) to achieve rail-to-rail common-mode input range extending 100 mV beyond both supply rails across 2.4 V–5.5 V operation. Its class AB output stage enables rail-to-rail swing - delivering ≤15 mV from rails into 10-kΩ loads.
It features a resistive open-loop output impedance (~100 Ω at 10 MHz), which reduces peaking and improves phase margin under capacitive loading. Overload recovery time is specified at 200 ns, and it includes integrated RF/EMI filtering plus 4-kV HBM ESD protection - critical for industrial and automotive-sensing nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 10 MHz typical - supports stable unity-gain and moderate-gain configurations up to ~1 MHz with adequate phase margin. |
| Supply Voltage Range | 2.4 V to 5.5 V - compatible with single-cell Li-ion, 3.3-V, and 5-V systems without level-shifting. |
| Input Bias Current | 1 pA typical - enables high-impedance sensor interfacing (e.g., photodiodes, pH electrodes) without significant offset error. |
| Quiescent Current | 600 μA per amplifier - allows dual-channel amplification in ultra-low-power portable devices with minimal battery drain. |
| Input Voltage Noise | 8.7 nV/√Hz at 10 kHz - suitable for medium-bandwidth precision signal chains where thermal noise dominates. |
| Output Swing | Within 15 mV of rails (VS = 5.5 V, RL = 10 kΩ) - maximizes dynamic range for ADC driving in low-voltage systems. |
| Open-Loop Output Impedance | ~100 Ω at 10 MHz - provides predictable frequency response with capacitive loads and simplifies compensation. |
Pinout & Package
Package: SOIC-8 (D package), body size 3.91 mm × 4.90 mm, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; rail-to-rail capable with defined settling and overload recovery. |
| 2 | –IN A | Inverting input, channel A - accepts feedback network or inverted signal path; matched to +IN A for CMRR optimization. |
| 3 | +IN A | Noninverting input, channel A - high-impedance node (1 pA bias) for sensor or reference connections. |
| 4 | V– | Negative supply or ground - common return for both amplifiers; must be low-impedance to maintain PSRR and noise performance. |
| 5 | +IN B | Noninverting input, channel B - electrically isolated from channel A; supports independent dual-signal processing. |
| 6 | –IN B | Inverting input, channel B - symmetric function to Pin 2; enables matched dual instrumentation or filter topologies. |
| 7 | OUT B | Amplifier B output - fully independent output stage; no crosstalk with OUT A (≥100 dB DC channel separation). |
| 8 | V+ | Positive supply - powers both amplifiers; internal regulation ensures consistent biasing across 2.4–5.5 V range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input range | Extends 100 mV beyond both supply rails - eliminates need for level-shifting in single-supply 3.3-V or 5-V systems. |
| Resistive open-loop output impedance | ~100 Ω at 10 MHz - suppresses resonance with capacitive loads and enables stable operation up to 300 pF without external compensation. |
| Integrated RFI/EMI filter | On-chip filtering rejects >100 MHz interference - critical for reliable operation near switching regulators or wireless modules. |
| No phase reversal on overdrive | Guaranteed behavior during input overvoltage - prevents latch-up or erroneous control signals in fault conditions. |
| 4-kV HBM ESD rating | Robust handling of human-body discharge - reduces board-level protection requirements in industrial and automotive assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6272IDR | Lower GBW (2 MHz), lower IQ (170 μA), same rail-to-rail I/O and package - but no integrated RFI filter or EMI rejection. | Better suited for ultra-low-power, low-bandwidth sensor nodes where EMI immunity is not critical. | Select MCP6272IDR only when bandwidth <2 MHz suffices and EMI robustness is secondary to quiescent current minimization. |
| TLV9062IDR | Higher GBW (10 MHz), lower VOS (±0.3 mV typ), same supply range - but higher IQ (560 μA per amp) and no specified RFI filter. | Preferred for precision DC-coupled applications demanding tighter offset and drift, but less tolerant of high-frequency noise. | Choose TLV9062IDR when offset accuracy and CMRR (>103 dB) outweigh EMI hardening and ultra-low IQ requirements. |
Compared with MCP6272IDR and TLV9062IDR, the MCP6292IDR uniquely balances 10-MHz bandwidth, 1-pA input bias, integrated RFI filtering, and 4-kV HBM protection - making it the optimal choice for noise-prone, battery-operated, wide-temperature sensing systems where reliability and signal fidelity are co-prioritized.

FAQ
What is the maximum capacitive load the MCP6292IDR can drive stably?
The MCP6292IDR maintains stability with capacitive loads up to 300 pF, thanks to its resistive open-loop output impedance and optimized internal compensation. This is verified in Figure C025 and C026 of the SBOS879D datasheet, showing overshoot remains within ±60% across that range. For loads >300 pF, external isolation resistor or feedback capacitor may be required. The MCP6292IDR's architecture avoids the peaking common in traditional op amps under capacitive loading.
Does the MCP6292IDR support true rail-to-rail input at 2.4-V supply?
Yes - the MCP6292IDR guarantees rail-to-rail input common-mode range from (V–) – 0.1 V to (V+) + 0.1 V across its full 2.4 V–5.5 V supply range, including at 2.4 V. This is confirmed in Section 7.7 (Electrical Characteristics) of the datasheet, where VCM min/max values are explicitly specified at VS = 2.4 V. The complementary input stage ensures functionality even at minimum supply.
What is the overload recovery time specification for the MCP6292IDR?
The MCP6292IDR has a typical overload recovery time of 200 ns, defined as the time required to return from saturation to linear operation after an overdrive event. This value is documented in Section 7.7 (Electrical Characteristics) under "Overload recovery time" and validated in Figure C036 (Overload Recovery). It enables fast settling in transient-heavy applications like motor current sensing or burst-mode signal acquisition.
Is the MCP6292IDR pin-compatible with other dual op amps in SOIC-8 packages?
No - the MCP6292IDR uses a non-standard SOIC-8 pinout optimized for dual independent amplifiers (Pins 1/2/3/4 for Channel A; Pins 5/6/7/4 for Channel B, sharing V–). It is not pin-compatible with industry-standard dual op amps like LM358 or TLV2372. Layout must follow the exact pin mapping in Section 6 (Pin Configuration and Functions) of SBOS879D to ensure correct channel routing and supply connection.
How does the integrated RFI filter in the MCP6292IDR improve system-level EMI immunity?
The MCP6292IDR's integrated RFI filter attenuates high-frequency interference (>100 MHz) before it reaches the input stage, as demonstrated by its EMIRR+ curve (Figure C041) showing >80 dB rejection at 900 MHz. This eliminates the need for external ferrite beads or RC filters in space-constrained designs - directly improving immunity to GSM, Bluetooth, and switching regulator noise without sacrificing bandwidth or adding bill-of-materials cost. The MCP6292IDR achieves this without degrading DC precision or AC performance.
