Product details
Overview
MCP6292IDDFR 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 engineers reviewing the MCP6292IDDFR datasheet, MCP6292IDDFR pinout, MCP6292IDDFR application, or MCP6292IDDFR equivalent, key selection criteria include capacitive-load stability (up to 300 pF), –40°C to 125°C extended temperature operation, rail-to-rail swing with ≤15 mV from rails (at 10 kΩ), and integrated RFI/EMI filtering for noisy environments.
Technical Context
The MCP6292IDDFR uses 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 V–5.5 V operation. Its class AB output stage enables full rail-to-rail swing with low open-loop output impedance (100 Ω at 10 MHz), improving stability into capacitive loads.
It features unity-gain stability, no phase reversal under overdrive, and 4-kV HBM ESD protection. The device exhibits 200-ns overload recovery time and maintains ≥55° phase margin up to 300 pF load capacitance - critical for driving ADC inputs and photodiode transimpedance stages without external compensation.
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 20-dB gain margin. |
| Supply Voltage Range | 2.4 V to 5.5 V - compatible with Li-ion, USB, and industrial 3.3 V/5 V rails without level-shifting. |
| Input Offset Voltage | ±0.3 mV (typ), ±5 mV (max over –40°C to 125°C) - enables accurate DC-coupled amplification in precision sensor bridges. |
| Quiescent Current | 600 µA per channel (typ) - allows dual-channel operation in sub-1.3-mA total system power budgets. |
| Input Voltage Noise | 8.7 nV/√Hz at 10 kHz - suitable for low-frequency sensor signals where thermal noise dominates. |
| Output Swing | Within 15 mV of rails (at 10 kΩ, VS = 5.5 V) - maximizes dynamic range into SAR or delta-sigma ADCs. |
| Capacitive Load Drive | Stable up to 300 pF - eliminates need for isolation resistors when driving long traces or ADC input capacitance. |
Pinout & Package
SOT-23-8 (DDF) package: 1.60 mm × 2.90 mm body, 0.65 mm pitch, surface-mount, thermally enhanced layout with exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; rail-to-rail capable with 100-Ω open-loop impedance. |
| 2 | –IN A | Inverting input, channel A - accepts feedback network or inverting configuration signals; 1-pA bias current enables high-Z sources. |
| 3 | +IN A | Noninverting input, channel A - connects to reference, sensor, or signal source; rail-to-rail common-mode range includes V– and V+. |
| 4 | V– | Negative supply or ground - serves as return path for both channels; must be low-impedance for PSRR integrity. |
| 5 | +IN B | Noninverting input, channel B - independent of channel A; supports dual-sensor or differential pair configurations. |
| 6 | –IN B | Inverting input, channel B - used for second feedback loop or matched gain setting; same 1-pA bias as channel A. |
| 7 | OUT B | Amplifier B output - fully independent output stage; shares V–/V+ rails but no crosstalk above 100 dB at DC. |
| 8 | V+ | Positive supply - powers both amplifiers; 2.4–5.5 V range allows direct connection to regulated 3.3 V or 5 V supplies. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input range | Extends 100 mV beyond V– and V+ across full 2.4–5.5 V supply - enables direct interface to 0–VREF sensor outputs without level shifters. |
| Resistive open-loop output impedance | 100 Ω at 10 MHz - simplifies compensation and improves phase margin into capacitive loads vs. traditional op-amps with reactive Zo. |
| Integrated RFI/EMI filter | On-chip filtering rejects >100 MHz RF interference - reduces need for external ferrite beads or RC filters in automotive or industrial EMI environments. |
| No phase reversal on overdrive | Output remains monotonic during input overvoltage - prevents latch-up or false triggering in comparator-like applications or transient fault conditions. |
| Extended temperature range | –40°C to +125°C operation - qualified for under-hood automotive, HVAC control, and industrial motor drive monitoring. |

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-MHz GBW but higher 530-µA/channel IQ; no integrated EMI filter; 1.8-V min supply. | Better for ultra-low-voltage (1.8–5.5 V) designs; less robust in high-EMI automotive cabins without external filtering. | Choose TLV9062IDR only if supply drops below 2.4 V or EMI environment is controlled. |
| OPA2333AIDR | Zero-drift architecture; 0.02-µV/°C drift vs. MCP6292IDDFR's ±1.1-µV/°C; 350-µA/channel IQ; 350-kHz GBW. | Superior for DC-precision applications (e.g., weigh scales); insufficient bandwidth for fast sensor sampling or audio. | Choose OPA2333AIDR only when microvolt-level drift matters more than 10-MHz bandwidth or 600-µA power budget. |
Compared with TLV9062IDR and OPA2333AIDR, the MCP6292IDDFR uniquely balances 10-MHz bandwidth, 600-µA/channel efficiency, integrated EMI rejection, and –40°C to 125°C operation - making it optimal for cost-sensitive, noise-prone, wide-temperature industrial and automotive sensor nodes.

FAQ
What is the maximum capacitive load the MCP6292IDDFR can drive stably?
The MCP6292IDDFR is stable driving up to 300 pF of capacitive load without external compensation, as verified by overshoot and phase margin measurements in the datasheet (Figure C025/C026 and Figure 29). This capability stems from its resistive open-loop output impedance, which avoids peaking common in conventional op-amps. For loads exceeding 300 pF, a small series resistor (e.g., 10–50 Ω) at the output is recommended. The MCP6292IDDFR's behavior remains predictable and monotonic even under heavy capacitive loading.
Does the MCP6292IDDFR support true rail-to-rail input with 2.4-V supply?
Yes, the MCP6292IDDFR supports rail-to-rail input operation down to 2.4 V supply, with common-mode voltage range extending 100 mV beyond both V– and V+ rails across the full 2.4–5.5 V range. At 2.4 V, this means the input accepts signals from –0.1 V to +2.5 V. This is achieved via a complementary N/P-channel input stage, enabling direct interfacing with sensors or references operating near supply rails - a capability confirmed in Section 8.3.1 and Table 7.7 of the MCP6292IDDFR datasheet.
What is the overload recovery time specification for the MCP6292IDDFR?
The MCP6292IDDFR has a typical overload recovery time of 200 ns, defined as the time required for the output to return from saturation to linear operation after an overdrive condition. This fast recovery minimizes propagation delay in transient-heavy applications like pulse-width modulated sensor excitation or fault detection circuits. The value is measured under standard conditions (VS = 5 V, G = 1) and is consistent across temperature - a key differentiator versus slower legacy op-amps. This parameter is explicitly listed in Table 7.7 under "Overload recovery time (tOR)".
Is the MCP6292IDDFR pin-compatible with other packages in the MCP629x family?
No, the MCP6292IDDFR (SOT-23-8, DDF) is not pin-compatible with SOIC-8 or VSSOP-8 variants of the MCP6292. While all share identical pin functions (e.g., Pin 1 = OUT A, Pin 2 = –IN A), the SOT-23-8 (DDF) has a different pinout order than SOIC-8 (D) and VSSOP-8 (DGK) - specifically, Pin 4 is V– and Pin 5 is +IN B in DDF, whereas Pin 4 is V– and Pin 5 is –IN B in D/DGK packages. PCB layout must match the DDF mechanical footprint and pin mapping; migration requires board revision.
How does the integrated RFI/EMI filter in the MCP6292IDDFR improve system-level immunity?
The MCP6292IDDFR integrates an on-die RFI/EMI rejection filter that attenuates high-frequency interference (>100 MHz) before it reaches the input stage, reducing susceptibility to GSM, Wi-Fi, and switching regulator noise. Measured EMIRR+ exceeds 80 dB at 900 MHz (Figure C041), allowing the MCP6292IDDFR to maintain signal integrity in electrically noisy environments - such as automotive cabins or industrial motor drives - without requiring external RC filters or ferrite beads. This directly lowers BOM count and layout complexity compared to unfiltered op-amps.
