Product details
Overview
MCP6292IDGKR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in single-supply systems. It delivers 10-MHz gain bandwidth, 600-μA per channel quiescent current, and 8.7 nV/√Hz input voltage noise at 10 kHz - enabling high-fidelity amplification in battery-powered sensor interfaces and analog front-ends for ADCs.
For engineers reviewing the MCP6292IDGKR datasheet, MCP6292IDGKR pinout, MCP6292IDGKR application, or MCP6292IDGKR equivalent, key selection criteria include its extended –40°C to 125°C operating range, 2.4 V to 5.5 V supply flexibility, unity-gain stability with capacitive loads up to 300 pF, and integrated RFI/EMI filtering for robust performance in noisy industrial and automotive environments.
Technical Context
The MCP6292IDGKR employs a complementary differential input stage (N- and P-channel pairs) to achieve rail-to-rail common-mode input range extending 100 mV beyond both supply rails across 2.4–5.5 V operation. Its class AB output stage enables rail-to-rail swing - delivering ≤15 mV from rails into 10-kΩ loads at 5.5 V.
It features resistive open-loop output impedance (~100 Ω at 10 MHz), which improves stability with capacitive loads versus conventional op-amps. Overload recovery time is 200 ns, and it includes 4-kV HBM ESD protection and no phase reversal under overdrive - critical for fault-tolerant sensing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 10 MHz typical - supports stable unity-gain and higher closed-loop configurations up to audio and low-speed data acquisition frequencies. |
| Supply Voltage Range | 2.4 V to 5.5 V - compatible with Li-ion, 3.3-V, and 5-V systems without level-shifting. |
| Input Bias Current | 1 pA typical - enables use with high-impedance sources like photodiodes and pH sensors without significant error. |
| Quiescent Current | 600 μA per channel - allows dual-channel precision amplification in power-constrained applications such as smoke detectors and portable medical devices. |
| Input Voltage Noise | 8.7 nV/√Hz at 10 kHz - ensures low-noise signal integrity for sensor signal conditioning and analog filters. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, HVAC, and industrial control environments. |
| Open-Loop Output Impedance | ~100 Ω at 10 MHz - provides predictable frequency response and improved phase margin with capacitive loads up to 300 pF. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65-mm lead pitch, thermally enhanced exposed pad for improved power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage circuitry; rail-to-rail swing capability minimizes headroom loss. |
| 2 | –IN A | Inverting input, channel A - used in inverting configurations or feedback networks; matched with +IN A for differential gain. |
| 3 | +IN A | Noninverting input, channel A - accepts high-impedance sensor signals; benefits from 1-pA bias current for minimal loading. |
| 4 | V– | Negative supply or ground reference - establishes common-mode baseline; supports single-supply operation down to 2.4 V total supply. |
| 5 | +IN B | Noninverting input, channel B - independent second channel for dual-sensor conditioning or signal buffering. |
| 6 | –IN B | Inverting input, channel B - enables separate inverting gain paths without cross-talk due to >100-dB DC channel separation. |
| 7 | OUT B | Amplifier B output - fully independent output stage; capable of driving separate loads or ADC inputs simultaneously. |
| 8 | V+ | Positive supply - powers both channels; internal regulation ensures consistent performance across 2.4–5.5 V range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input/output | Common-mode range extends 100 mV beyond rails; output swings within 15 mV of V+ or V– into 10-kΩ - maximizes dynamic range in low-voltage systems. |
| Integrated RFI/EMI filter | On-chip filtering suppresses high-frequency interference from switching regulators and RF sources - reduces need for external RC snubbers. |
| No phase reversal on overdrive | Output remains monotonic during input overvoltage - prevents latch-up or false triggering in safety-critical sensor monitoring. |
| Resistive open-loop output impedance | ~100 Ω output resistance enables stable operation with ≥300 pF capacitive loads - simplifies driving ADC inputs and long traces. |
| 4-kV HBM ESD protection | Robust input protection eliminates need for external TVS diodes in board-level ESD-prone environments like industrial I/O modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9062IDR | Higher 10.3-MHz GBW but 530-μA/ch IQ; no integrated EMI filter; lower ESD rating (2-kV HBM). | Better for high-speed filtering but less robust in electrically noisy HVAC or automotive infotainment systems. | Choose TLV9062IDR when speed > noise immunity; MCP6292IDGKR preferred where EMI rejection and 4-kV HBM are mandatory. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift vs. ±1.1 µV/°C), but 17-µA/ch IQ and 350-kHz GBW - not unity-gain stable above 100 pF. | Suitable for DC-critical precision thermometry, but unsuitable for AC-coupled sensor signals or fast-settling ADC drivers. | Choose OPA2333AIDR only for ultra-low-drift DC applications; MCP6292IDGKR better balances speed, power, and stability for general-purpose signal chains. |
Compared with TLV9062IDR and OPA2333AIDR, the MCP6292IDGKR uniquely combines 10-MHz bandwidth, sub-1-pA bias current, integrated EMI filtering, and 4-kV HBM in a VSSOP-8 package - making it optimal for cost-sensitive, noise-immune, battery-operated industrial and safety-critical sensing.

FAQ
What is the maximum capacitive load the MCP6292IDGKR can drive while maintaining stability?
The MCP6292IDGKR maintains stable unity-gain operation with capacitive loads up to 300 pF, as verified by overshoot vs. load capacitance curves in the datasheet (Figure C025). This is enabled by its resistive open-loop output impedance (~100 Ω), which avoids the peaking common in traditional op-amps. For loads exceeding 300 pF, external isolation resistors are recommended.
Does the MCP6292IDGKR support true rail-to-rail input common-mode range across its full supply voltage range?
Yes - the MCP6292IDGKR achieves rail-to-rail input common-mode range from (V–) – 0.1 V to (V+) + 0.1 V across its entire 2.4 V to 5.5 V supply range. This is implemented via a complementary N/P-channel input stage, allowing direct interfacing with sensors referenced to ground or V+ without external level-shifting circuitry.
What is the overload recovery time specification for the MCP6292IDGKR, and why does it matter?
The MCP6292IDGKR has a specified overload recovery time of 200 ns. This parameter defines how quickly the output returns to linear operation after saturation - critical in applications like overcurrent detection or fast pulse amplification where delayed recovery could cause missed events or distorted waveforms in the MCP6292IDGKR signal path.
How does the integrated RFI/EMI filter in the MCP6292IDGKR improve system-level EMC performance?
The MCP6292IDGKR incorporates an on-die RFI/EMI rejection filter that attenuates high-frequency interference (e.g., from switch-mode power supplies or radio transceivers) before it reaches the input stage. This reduces susceptibility to RF rectification and eliminates the need for external ferrite beads or RC filters - directly improving EMC compliance in compact, densely packed PCB layouts using the MCP6292IDGKR.
Is the MCP6292IDGKR pin-compatible with other members of the MCP629x family, such as the MCP6292IDR?
Yes - the MCP6292IDGKR (VSSOP-8) shares identical pinout and electrical specifications with the SOIC-8 variant MCP6292IDR. Both use the same DGK and D package footprints per TI's Device Information table, enabling drop-in replacement in existing designs where thermal or space constraints favor the smaller VSSOP package.
