Product details
Overview
LMC6036IMTX/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 20fA typical input bias current, 126dB open-loop voltage gain, and 2.7V rail-to-rail swing into 600Ω at 2.7V supply - enabling high-impedance buffering in battery-powered medical instrumentation and portable active filters.
For engineers reviewing the LMC6036IMTX/NOPB datasheet, LMC6036IMTX/NOPB pinout, LMC6036IMTX/NOPB application, or LMC6036IMTX/NOPB equivalent, key selection criteria include ultra-low input current for high-Z sensor interfaces, guaranteed 2.7V operation with 200mV rail margin into 600Ω, wide common-mode range (–0.1V to +2.3V at 2.7V), THD of 0.01% at 10kHz, and quad-channel integration in TSSOP-14 package for space-constrained analog signal chains.
Technical Context
The LMC6036IMTX/NOPB employs a CMOS input stage delivering femtoampere-level input bias current and operates across a 2.0V–15.5V supply range, supporting true single-supply use down to end-of-life battery voltages (e.g., 2.7V for three NiMH cells). Its rail-to-rail output stage maintains 200mV headroom from either rail into 600Ω at 2.7V, while sustaining 126dB open-loop gain and 1.4MHz gain-bandwidth product.
It features a wide input common-mode voltage range extending to –0.1V below V– and +2.3V above V– at 2.7V supply, enabling direct interfacing with ground-referenced sensors. The device exhibits 0.01% total harmonic distortion at 10kHz with 2kΩ load and achieves 130dB channel-to-channel isolation, critical for multi-channel filtering and differential driver applications.

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 (1pA vs 20fA); lower GBW (6.4MHz); no guaranteed 2.7V operation. | Less suitable for >10MΩ sensor buffering; better for higher-speed, moderate-impedance signal chains. | Choose TLV2464IDR when bandwidth >1MHz is required and input impedance <1MΩ. |
| OPA2333PWR | Zero-drift architecture; 0.02µV/°C offset drift; higher quiescent current (17µA vs 2.7mA per channel). | Superior DC precision but higher power; not optimized for rail-to-rail swing into 600Ω at 2.7V. | Choose OPA2333PWR for microvolt-level DC stability where power budget allows. |
Compared with TLV2464IDR and OPA2333PWR, LMC6036IMTX/NOPB uniquely balances femtoampere input leakage, guaranteed 2.7V rail-to-rail operation into 600Ω, and 1.4MHz bandwidth - making it optimal for battery-powered high-impedance analog front-ends where both precision and ultra-low power are mandatory.

FAQ
What is the minimum supply voltage for reliable operation of LMC6036IMTX/NOPB?
LMC6036IMTX/NOPB is fully specified and guaranteed to operate from 2.0V to 15.5V. At 2.7V - corresponding to end-of-life voltage for three-series NiMH/NiCd cells - it delivers rail-to-rail output swing into 600Ω with 200mV margin and maintains 126dB open-loop gain. Operation below 2.0V is not characterized and may result in degraded performance or failure to meet datasheet limits.
Does LMC6036IMTX/NOPB support true rail-to-rail input common-mode range?
LMC6036IMTX/NOPB does not support rail-to-rail input common-mode range. At 2.7V supply, its input common-mode voltage range is specified from –0.1V to +2.3V relative to V–, meaning it accepts inputs 0.1V below ground and up to 2.3V above ground. This enables ground-referenced sensor interfacing but excludes direct connection to V+ without level-shifting.
What is the maximum capacitive load LMC6036IMTX/NOPB can drive without oscillation?
LMC6036IMTX/NOPB is not unconditionally stable into large capacitive loads. As a unity-gain follower, it may oscillate with >100pF load. Stability is restored using series output resistance (50–100Ω) plus feedback capacitor (5–10pF) from output to inverting input, or by adding a pullup resistor to V+. These techniques enable reliable operation into >1nF loads in active filter and cable-driving applications.
How does LMC6036IMTX/NOPB perform in active filter applications compared to standard rail-to-rail op amps?
LMC6036IMTX/NOPB excels in active filters due to its combination of 20fA input bias current (enabling high-R/low-C designs), 0.01% THD at 10kHz, and 1.4MHz GBW. Unlike many rail-to-rail op amps, it sustains high open-loop gain into 600Ω loads - preventing distortion rise under heavy loading, as verified in Sallen-Key low-pass and high-pass filter benchmarks at 3kHz and 300Hz respectively.
Is LMC6036IMTX/NOPB qualified for automotive applications?
LMC6036IMTX/NOPB is not AEC-Q100 qualified. Only the LMC6035-Q1 variant (dual-channel) carries AEC-Q100 Grade 3 qualification. For automotive use, designers must select LMC6035-Q1 or alternative qualified quad op amps; LMC6036IMTX/NOPB is intended for industrial, medical, and consumer portable equipment.
