Product details
Overview
LMC6032IN/NOPB from Texas Instruments is a dual CMOS operational amplifier optimized for high-impedance, low-drift signal conditioning in single- or dual-supply systems. It delivers 126dB open-loop voltage gain into 2kΩ loads, ultra-low 40fA input bias current, and rail-to-rail input common-mode range extending to V−. It is used in medical instrumentation front-ends and precision current-to-voltage conversion where leakage and offset drift must be minimized.
For engineers reviewing the LMC6032IN/NOPB datasheet, LMC6032IN/NOPB pinout, LMC6032IN/NOPB application, or LMC6032IN/NOPB equivalent, key selection criteria include input bias current stability over temperature, output swing capability into 600Ω loads, offset voltage drift ≤2.3μV/°C, and compatibility with 5V/±5V/±7.5V supply configurations.
Technical Context
The LMC6032IN/NOPB employs a proprietary CMOS input stage with differential front-end architecture enabling true rail-to-rail input operation down to V− while maintaining ultra-low input bias current. Its output stage supports sourcing/sinking into 600Ω loads without oscillation when properly compensated.
It features a 1.4MHz gain-bandwidth product and 1.1V/μs slew rate at ±7.5V supplies, with phase margin ≥50° under specified capacitive load conditions. Input voltage noise is 22nV/√Hz at 1kHz, and common-mode rejection exceeds 83dB at DC.

| Input common-mode range | Extends to V− - allows direct interface with grounded sensors and single-supply transducer outputs |
| Quiescent current | 375μA per amplifier - enables low-power portable instrumentation without sacrificing input performance |
Pinout & Package
LMC6032IN/NOPB is packaged in an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and standard through-hole mounting. Pin spacing is 0.1 inch, lead finish is matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin 3) | Noninverting input, Channel A | High-impedance node accepting signals down to V−; requires guard ring layout for sub-pA leakage control |
| –IN A (Pin 2) | Inverting input, Channel A | Feedback node for precision amplification; sensitive to stray capacitance above 10pF |
| OUT A (Pin 1) | Output, Channel A | Capable of ±22mA short-circuit current; requires series resistor for >100pF capacitive load stability |
| V− (Pin 4) | Negative power supply | Reference for input common-mode range; must be decoupled with 0.1μF ceramic near package |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent high-Z input identical to Pin 3; usable for differential or dual-path signal processing |
| –IN B (Pin 6) | Inverting input, Channel B | Second feedback node; crosstalk to Channel A is –130dB at 1kHz |
| OUT B (Pin 7) | Output, Channel B | Matched performance to OUT A; supports independent load driving up to 600Ω |
| V+ (Pin 8) | Positive power supply | Highest potential rail; must not exceed 16V absolute maximum; avoid direct connection to output above 13V |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Includes V− and extends within 1.9V of V+, enabling ground-referenced sensor interfacing on single 5V supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual CMOS op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6042IN/NOPB | Higher 2.5MHz GBW, 2.5V/μs slew rate, but 100fA input bias current (2.5× higher) | Better for wideband active filters; less suitable for pA-level current sensing | Select LMC6042IN/NOPB only when bandwidth >1.4MHz is required and input leakage tolerance >40fA is acceptable |
| TLC272CP | Lower 1.8mV max offset voltage, but 1pA input bias current (25× higher) and no V−-to-rail input | Preferred for low-offset DC amplification where input impedance >100GΩ is sufficient | Choose TLC272CP when offset voltage is critical and input common-mode range need not reach ground |
Compared with LMC6032IN/NOPB, LMC6042IN/NOPB trades ultra-low bias current for higher speed, while TLC272CP sacrifices input range and leakage performance for lower initial offset - making LMC6032IN/NOPB uniquely suited for high-Z, low-drift, rail-to-rail-input applications.

FAQ
What is the maximum capacitive load the LMC6032IN/NOPB can drive without oscillation?
The LMC6032IN/NOPB can reliably drive up to 100pF with proper compensation. For loads exceeding 100pF, a 50Ω–100Ω series resistor at the output plus a 5pF–10pF feedback capacitor from output to inverting input restores phase margin. Uncompensated operation with >200pF loads risks instability, especially in unity-gain follower configurations. The LMC6032IN/NOPB datasheet specifies this behavior in Figure 5-13 through Figure 5-16.
Does the LMC6032IN/NOPB support true rail-to-rail output swing?
No, the LMC6032IN/NOPB does not provide rail-to-rail output swing. Its output voltage swing is specified as 4.20V to 4.87V (positive rail) and 0.10V to 0.25V (negative rail) at 5V supply with 2kΩ load. At ±7.5V supplies, it delivers 13.50V to 14.63V and 0.26V to 0.45V. Output swing is load-dependent and degrades with 600Ω loads, but input common-mode range does extend to V− - a key distinction confirmed in Section 5.6 of the LMC6032IN/NOPB datasheet.
Can the LMC6032IN/NOPB operate from a single 3.3V supply?
No, the LMC6032IN/NOPB is not specified for 3.3V single-supply operation. Its recommended minimum single-supply voltage is 4.75V, and absolute maximum is 16V. Operation below 4.75V may result in degraded open-loop gain, reduced output swing, and increased input bias current. For 3.3V systems, consider TI's LMP7721 or OPA376 families, which are explicitly characterized down to 2.7V. This requirement is clearly stated in Section 5.3 (Recommended Operating Conditions) of the LMC6032IN/NOPB datasheet.
How does the LMC6032IN/NOPB compare to the LM358 in pin compatibility and performance?
The LMC6032IN/NOPB is pin-compatible with the LM358 in the 8-pin PDIP and SOIC packages, sharing identical pinout for +IN A, –IN A, OUT A, V–, +IN B, –IN B, OUT B, and V+. However, it delivers superior performance: 40fA vs 45nA input bias current (10⁶× lower), 126dB vs 100dB open-loop gain, and rail-to-rail input operation including V− - whereas LM358 input range stops ~1.5V above V−. These differences make LMC6032IN/NOPB suitable for high-precision upgrades of existing LM358 designs where leakage and offset drift dominate error budgets.
Is the LMC6032IN/NOPB suitable for use in automotive applications?
The LMC6032IN/NOPB is not qualified for automotive applications. It is rated for industrial temperature range (–40°C to +85°C) but lacks AEC-Q100 qualification, automotive-grade screening, or guaranteed PPAP documentation. Its datasheet contains no automotive-specific reliability testing, failure-in-time (FIT) data, or stress-test results per JESD22. For automotive sensor interfaces, TI recommends the TLV2462-Q1 or OPA2333-Q1, which are explicitly AEC-Q100 Grade 2 qualified. This limitation is documented in the "Important Notice" section of the LMC6032IN/NOPB datasheet.
