Product details
Overview
LMC6036IMX/NOPB from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for low-voltage, single-supply operation (2.0V–15.5V), featuring 20 fA typical input bias current, 126 dB open-loop voltage gain, and rail-to-rail swing into 600 Ω at 2.7 V - enabling high-precision buffering in battery-powered medical instrumentation and portable sensor interfaces.
For engineers reviewing the LMC6036IMX/NOPB datasheet, LMC6036IMX/NOPB pinout, LMC6036IMX/NOPB application, or LMC6036IMX/NOPB equivalent, key selection criteria include ultra-low input current for high-Z source interfacing, guaranteed 2.7 V operation matching end-of-life NiMH/NiCd battery voltage, rail-to-rail output drive into 600 Ω loads, and quad-channel integration for space-constrained signal conditioning stages.
Technical Context
The LMC6036IMX/NOPB employs a CMOS input stage with femtoampere-level leakage, enabling direct interface with photodiode, pH electrode, and piezoelectric sensors without guard rings or bootstrapping. Its rail-to-rail output stage uses complementary MOSFETs to achieve 200 mV from either rail at 2.7 V/600 Ω, while maintaining >75 V/mV open-loop gain under same conditions.
It operates across –40°C to +85°C with specified performance at 2.7 V, 3 V, 5 V, and 15 V supplies, and supports both single-supply (2.0V–15.5V) and split-supply (±1V–±7.75V) configurations. Input common-mode range extends to –0.1 V below V– and +2.3 V above V– at 2.7 V supply, enabling ground-referenced inputs in single-supply systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad CMOS op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher input bias current (1 pA vs 20 fA); lower open-loop gain (106 dB); 2.5 V min supply | Less suitable for pA-level current sensing or >10 s RC time constants | Preferred where cost sensitivity outweighs ultra-low IB requirement and 2.5 V operation suffices |
| OPA2333PWR | Zero-drift architecture; 0.02 µV/°C offset drift; higher quiescent current (17 µA/ch vs 675 µA/ch) | Better DC precision but higher power; not rail-to-rail into 600 Ω at 2.7 V | Chosen when microvolt-level offset stability over temperature is critical, and supply >3 V is available |
Compared with TLV2464IDR and OPA2333PWR, LMC6036IMX/NOPB uniquely balances femtoampere input bias, rail-to-rail 600 Ω drive at 2.7 V, and 126 dB gain-making it optimal for battery-powered high-impedance sensor interfaces where leakage-limited accuracy dominates over zero-drift or ultra-low IQ requirements.

FAQ
What is the minimum supply voltage for reliable operation of LMC6036IMX/NOPB?
The LMC6036IMX/NOPB is fully specified from 2.0 V to 15.5 V supply. At 2.0 V, key parameters including input bias current, open-loop gain, and output swing remain functional - though output swing degrades to ~300 mV from rails into 600 Ω. The 2.7 V rating corresponds to end-of-life voltage for three NiMH/NiCd cells, ensuring robust operation across full battery discharge.
Does LMC6036IMX/NOPB support true rail-to-rail input common-mode range?
No - LMC6036IMX/NOPB features rail-to-rail *output* swing, but its input common-mode range is limited to –0.1 V to +2.3 V at 2.7 V supply. This allows ground-referenced inputs in single-supply systems but does not extend to the positive rail. For full rail-to-rail input, consider TI's LMC6484 or OPA4340 families.
Can LMC6036IMX/NOPB drive capacitive loads without oscillation?
LMC6036IMX/NOPB can oscillate with >100 pF capacitive loads in unity-gain follower configuration. Stability is restored by adding a 50–100 Ω series resistor at the output and/or a 5–10 pF feedback capacitor from output to inverting input. Figure 7-1 in the datasheet provides validated compensation networks for loads up to 1 nF.
What is the thermal resistance (θJA) of LMC6036IMX/NOPB in SOIC-14 package?
The LMC6036IMX/NOPB in SOIC-14 (D package) has a junction-to-ambient thermal resistance (θJA) of 83.0 °C/W under standard JEDEC JESD51-2 PCB conditions (2s2p copper). This value assumes 1-inch² copper pad on top layer with 2 oz copper and 2 internal planes - actual board layout may reduce θJA by 15–30% with enhanced thermal vias.
Is LMC6036IMX/NOPB qualified for automotive applications?
LMC6036IMX/NOPB is not AEC-Q200 qualified. However, the LMC6035-Q1 variant (dual-channel) is AEC-Q100 Grade 3 qualified. For automotive-grade quad op amp alternatives, TI recommends the TLV2774-Q1 or OPA4188-Q1, which offer similar rail-to-rail performance with full automotive qualification.
