Product details
Overview
MCP6292IDGKT 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 amplifier 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 engineers reviewing the MCP6292IDGKT datasheet, MCP6292IDGKT pinout, MCP6292IDGKT application, or MCP6292IDGKT equivalent, key selection criteria include its extended –40°C to 125°C operating range, 2.4 V to 5.5 V supply flexibility, resistive open-loop output impedance for stable capacitive loading, and integrated RFI/EMI filtering for noisy environments.
Technical Context
The MCP6292IDGKT 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 its full 2.4–5.5 V supply range. This architecture enables robust operation in single-supply configurations where input signals approach V– or V+.
Its class AB output stage delivers rail-to-rail swing - within 15 mV of either rail into 10 kΩ - and features a resistive open-loop output impedance (~100 Ω at 10 MHz), reducing sensitivity to capacitive load-induced instability. Overload recovery time is specified at 0.2 µs, supporting fast transient response in closed-loop sensing applications.
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 phase margin ≥55°. |
| 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 (e.g., photodiodes, pH electrodes) without significant offset error. |
| Quiescent current per channel | 600 µA typical - allows dual-amplifier operation in ultra-low-power designs (e.g., smoke detectors, portable medical sensors). |
| Input voltage noise density | 8.7 nV/√Hz at 10 kHz - suitable for medium-bandwidth precision amplification where thermal noise dominates. |
| Open-loop output impedance | ~100 Ω at 10 MHz - improves stability with capacitive loads up to 300 pF without external compensation. |
| Operating temperature | –40°C to 125°C - qualified for automotive under-hood, industrial control, and HVAC applications. |
Pinout & Package
Package: 8-pin VSSOP (DGK), body size 3.00 mm × 3.00 mm - compact surface-mount footprint with 0.65 mm lead pitch, optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry; rail-to-rail swing capability minimizes headroom loss in ADC driver stages. |
| 2 | –IN A | Inverting input, channel A - used in transimpedance, difference, or inverting gain configurations; 1 pA bias current preserves high-Z source integrity. |
| 3 | +IN A | Noninverting input, channel A - accepts signals from sensors or reference dividers; rail-to-rail common-mode range supports direct connection to V– or V+ referenced sources. |
| 4 | V– | Negative supply or ground - serves as return path for both amplifiers; must be low-impedance to maintain PSRR >80 dB. |
| 5 | +IN B | Noninverting input, channel B - independent input for second signal path; enables dual-sensor monitoring or dual-stage filtering. |
| 6 | –IN B | Inverting input, channel B - matches channel A electrical characteristics for matched gain/phase response in differential pair implementations. |
| 7 | OUT B | Amplifier B output - electrically isolated from OUT A; supports independent load driving or cascaded gain stages. |
| 8 | V+ | Positive supply - powers both amplifiers; 2.4–5.5 V range allows direct interface with microcontroller I/O domains or regulated LDO outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Common-mode range extends 100 mV beyond V– and V+, and output swings to within 15 mV of either rail into 10 kΩ - maximizes dynamic range in low-voltage systems. |
| Integrated RFI/EMI filter | On-chip filtering suppresses high-frequency interference (e.g., GSM bursts, switching regulator noise) without external RC networks - reduces layout sensitivity. |
| No phase reversal in overdrive | Output remains monotonic during input overvoltage conditions - prevents latch-up or false triggering in comparator-like sensor threshold detection. |
| Resistive open-loop output impedance | ~100 Ω output resistance enables stable operation with capacitive loads up to 300 pF - eliminates need for isolation resistors in ADC buffer applications. |
| High ESD protection | ±4-kV HBM rating - withstands handling and board-level ESD events without degradation, improving manufacturing yield and field reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6272-E/SN | Lower 3.5-MHz GBW, 300 µA IQ, same VSSOP-8 package and rail-to-rail I/O - reduced bandwidth and noise (11 nV/√Hz). | Better suited for sub-100-kHz sensor interfaces where ultra-low power dominates over speed/noise. | Select when supply current <600 µA/channel is critical and 10-MHz bandwidth is unnecessary. |
| TLV9062IDGKR | Higher 10-MHz GBW, 530 µA IQ, same VSSOP-8, but lower input bias current (0.5 pA) and higher ESD rating (±6-kV HBM). | Preferred for high-impedance pH or ion-selective electrode circuits requiring sub-pA bias and enhanced ruggedness. | Choose when superior input bias current or industrial-grade ESD immunity is required, accepting minor cost premium. |
Compared with MCP6272-E/SN, the MCP6292IDGKT provides 2.9× higher bandwidth and 25% lower noise for demanding signal chains; versus TLV9062IDGKR, it trades 0.5 pA lower bias current for broader temperature qualification (–40°C to 125°C vs –40°C to 125°C identical) and proven EMI rejection in automotive-grade designs.

FAQ
What is the maximum capacitive load the MCP6292IDGKT can drive stably?
The MCP6292IDGKT maintains stable operation with capacitive loads up to 300 pF due to its resistive open-loop output impedance (~100 Ω). Typical overshoot remains below 60% at 300 pF, and phase margin stays ≥55° - eliminating need for series isolation resistors in ADC buffer or cable-driving applications.
Does the MCP6292IDGKT support true rail-to-rail input with 2.4 V supply?
Yes. The MCP6292IDGKT guarantees rail-to-rail input common-mode range from (V–) – 0.1 V to (V+) + 0.1 V across its full 2.4–5.5 V supply range. At 2.4 V, this means inputs function reliably from –0.1 V to +2.5 V - enabling direct interfacing with grounded sensors or reference dividers.
How does the MCP6292IDGKT handle input overdrive conditions?
The MCP6292IDGKT exhibits no phase reversal during input overdrive - its output remains monotonic even when inputs exceed the supply rails by up to 0.5 V. This behavior prevents false triggering in comparator-like configurations and ensures predictable recovery within 0.2 µs after overload.
Is the MCP6292IDGKT qualified for automotive applications?
Yes. The MCP6292IDGKT is specified for operation from –40°C to 125°C and features ±4-kV HBM ESD protection, making it suitable for automotive infotainment, body control modules, and cabin sensor systems where extended temperature and robustness are required.
What is the typical input offset voltage drift of the MCP6292IDGKT?
The MCP6292IDGKT has a typical input offset voltage drift of ±1.1 µV/°C over –40°C to 125°C. This low drift, combined with initial offset <±3 mV, ensures stable DC accuracy in temperature-varying environments such as HVAC control or industrial process monitoring without frequent recalibration.
