Product details
Overview
LMC6036IM/NOPB from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for low-voltage, single-supply operation (2.0V to 15.5V), featuring ultra-low input bias current (20 fA typical), 126 dB open-loop voltage gain, and rail-to-rail swing into 600 Ω loads - enabling high-precision buffering in battery-powered medical instrumentation and portable sensor interfaces.
For engineers reviewing the LMC6036IM/NOPB datasheet, LMC6036IM/NOPB pinout, LMC6036IM/NOPB application, or LMC6036IM/NOPB equivalent, key selection criteria include input bias current stability over temperature, output drive capability at 2.7V supply, common-mode range extension to –0.1 V, and verified performance with 600 Ω and 2 kΩ loads per channel.
Technical Context
The LMC6036IM/NOPB employs a CMOS input stage delivering femtoampere-level input leakage, enabling accurate signal conditioning of high-impedance sources such as pH electrodes and piezoelectric sensors. Its rail-to-rail output stage uses complementary totem-pole transistors to achieve 200 mV from either rail at 2.7 V/600 Ω - critical for maximizing dynamic range in low-voltage systems.
It operates across –40°C to +85°C with guaranteed specifications at 2.7 V, 3 V, 5 V, and 15 V supplies, and supports dual-supply configurations (±1 V to ±7.75 V). The device maintains >75 V/mV open-loop gain at 600 Ω load over full temperature range, ensuring stable closed-loop accuracy in active filters and precision buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 15.5 V single supply - supports end-of-life NiMH/NiCd battery operation (2.7 V) and industrial 12–15 V rails. |
| Input Bias Current | 20 fA typical at 25°C - enables use of >10 MΩ feedback resistors without significant offset drift in high-Z sensor interfaces. |
| Rail-to-Rail Output Swing | 200 mV from either rail at 2.7 V/600 Ω - preserves >92% of full-scale dynamic range in 3 V systems driving moderate loads. |
| Open-Loop Gain | 1000 V/mV min at 600 Ω load, 25°C - ensures <0.1% gain error in unity-gain buffer configurations with heavy loading. |
| Gain Bandwidth Product | 1.4 MHz - supports stable 3 kHz active filter design (e.g., Sallen-Key LPF) with adequate phase margin (>48°). |
| Input Common-Mode Range | –0.1 V to +2.3 V at 2.7 V supply - allows direct interfacing to 0 V-referenced transducers without level-shifting circuitry. |
| Total Harmonic Distortion | 0.01% at 10 kHz, G = –10, RL = 2 kΩ - meets audio-grade linearity requirements in low-power differential drivers. |
Pinout & Package
LMC6036IM/NOPB is packaged in a 14-pin SOIC (D package) with standard industry pinout and thermal pad-compatible footprint. Pin numbering follows TI's conventional top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output A–D | Amplifier output channels; each capable of sourcing/sinking ≥4 mA and swinging within 200 mV of rails at 2.7 V/600 Ω. |
| 2, 6, 9, 13 | Inverting Input A–D | Differential input terminals; CMOS inputs with >10 TΩ impedance and 20 fA bias current enable high-Z node buffering. |
| 3, 5, 10, 12 | Noninverting Input A–D | Matched to inverting inputs; supports unity-gain follower, differential, and active filter configurations with minimal input error. |
| 4 | Positive Supply (V+) | Single-supply rail connection; accepts 2.0–15.5 V; decoupling capacitor required near pin for stability with capacitive loads. |
| 11 | Negative Supply (V–) | Ground reference for single-supply operation; must be connected to system GND; supports dual-supply operation down to –7.75 V. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 20 fA typical - eliminates resistor-induced offset errors in picoamp-level current measurement circuits. |
| Rail-to-rail output with 600 Ω drive | 200 mV headroom at 2.7 V - enables full-scale signal utilization in 3 V battery-powered data loggers and portable ECG front-ends. |
| Wide supply range (2.0–15.5 V) | Operates from depleted 3-cell NiMH (2.7 V) to industrial 12 V rails - simplifies BOM consolidation across portable and fixed equipment. |
| High open-loop gain stability | ≥75 V/mV at 600 Ω over –40°C to +85°C - ensures consistent loop gain and THD performance in active filters under thermal stress. |
| Low distortion at 10 kHz | 0.01% THD+N - supports clean analog signal paths in voice-band communication interfaces and sensor signal chains. |

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 (75 V/mV); 2.5 V min supply. | Less suitable for sub-picoamp sensor buffering; acceptable for general-purpose 3 V active filters. | Choose TLV2464IDR only when ultra-low IB is not required and cost is prioritized over precision. |
| OPA2333PWR | Zero-drift architecture; 0.02 µV/°C offset drift; higher quiescent current (17 µA per amp); 1.8 V min supply. | Better DC accuracy but higher power; unsuitable for multi-year battery operation where LMC6036IM/NOPB's 2.7 mA total IQ is critical. | Select OPA2333PWR when microvolt-level offset stability dominates over battery life and input leakage. |
Compared with TLV2464IDR and OPA2333PWR, LMC6036IM/NOPB uniquely balances femtoampere input leakage, rail-to-rail 600 Ω drive, and sub-3 mA total quiescent current - making it irreplaceable in long-life, high-impedance portable instrumentation where all three parameters are simultaneously constrained.

FAQ
What is the minimum operating supply voltage for LMC6036IM/NOPB?
The LMC6036IM/NOPB is specified to operate down to 2.0 V supply voltage, with full performance guaranteed at 2.7 V - matching the end-of-life voltage of three-series NiMH/NiCd cells. At 2.0 V, key parameters like open-loop gain and output swing degrade predictably but remain functional, providing design margin for brownout conditions.
Does LMC6036IM/NOPB support true rail-to-rail input common-mode range?
No - LMC6036IM/NOPB features rail-to-rail *output* swing but has a limited input common-mode range: –0.1 V to +2.3 V at 2.7 V supply. This allows the inputs to operate slightly below ground (enabling AC-coupled inputs) but does not extend fully to V+. For full rail-to-rail input, consider TI's LMC6484 or OPA4342 families.
Can LMC6036IM/NOPB drive capacitive loads without oscillation?
LMC6036IM/NOPB is not inherently unity-gain stable with large capacitive loads. Driving >100 pF directly may cause peaking or oscillation. TI recommends adding a 50–100 Ω series resistor at the output and/or a 5–10 pF feedback capacitor from output to inverting input to restore phase margin above 48°.
What is the thermal resistance (RθJA) of LMC6036IM/NOPB in SOIC package?
The LMC6036IM/NOPB in 14-pin SOIC (D package) has a junction-to-ambient thermal resistance (RθJA) of 83.0 °C/W, measured per JEDEC JESD51-2 with 1-inch² 2-oz copper on a standard test board. This value assumes proper PCB layout with thermal vias and adequate copper pour for heat dissipation.
Is LMC6036IM/NOPB qualified for automotive applications?
No - LMC6036IM/NOPB is not AEC-Q100 qualified. Only the LMC6035-Q1 variant (dual-channel) carries AEC-Q100 Grade 3 qualification. For automotive-grade quad op amps, TI recommends the TLV9064-Q1 or OPA4991-Q1, which offer comparable low-power performance with full automotive qualification.
