Product details
Overview
LMC6035ITLX/NOPB from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier in an 8-bump DSBGA (YAF) package, specified for 2.7V–15.5V single-supply operation. It delivers ultra-low input bias current (20 fA typ), 126 dB open-loop voltage gain, and rail-to-rail swing within 200 mV of either rail at 2.7V/600Ω - enabling high-impedance buffering in portable medical sensors and battery-powered instrumentation.
For engineers reviewing the LMC6035ITLX/NOPB datasheet, LMC6035ITLX/NOPB pinout, LMC6035ITLX/NOPB application, or LMC6035ITLX/NOPB equivalent, key selection criteria include femtoampere input leakage, 2.7V minimum supply compatibility, DSBGA thermal performance (RθJA = 103.1°C/W), and verified operation into 600Ω loads at end-of-life battery voltages.
Technical Context
The LMC6035ITLX/NOPB employs a CMOS input stage with gate-isolated p-channel inputs to achieve 20 fA typical input bias current and >10 TΩ input resistance. Its rail-to-rail output stage uses complementary MOSFETs in a totem-pole configuration, delivering 200 mV headroom at 600Ω under 2.7V supply - critical for low-voltage active filters and sensor front-ends.
It operates across –40°C to +85°C junction temperature with specified performance at 2.7V, 3V, 5V, and 15V supplies. The device supports single-supply use down to 2.0V and maintains usable gain and CMRR (>60 dB) even below 2.7V, providing margin for NiCd/NiMH battery discharge curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 15.5 V single supply - supports operation through full NiMH/NiCd battery discharge (0.9 V/cell × 3 cells = 2.7 V end-of-life). |
| Input Bias Current | 20 fA typical - enables use of MΩ-range resistors and nF-range capacitors in low-power active filters without DC error accumulation. |
| Open-Loop Gain | 126 dB typical - ensures <0.01% gain error in precision buffer and instrumentation amplifier configurations with 100× closed-loop gain. |
| Rail-to-Rail Output Swing | 200 mV from rails at 2.7 V/600 Ω - preserves dynamic range in 3 V systems driving audio transformers or ADC drivers. |
| Gain Bandwidth Product | 1.4 MHz - supports stable unity-gain buffer operation up to ~100 kHz with 100 pF capacitive load when compensated per TI AN-1112. |
| Input Common-Mode Range | –0.1 V to +2.3 V at 2.7 V supply - allows direct interfacing to 0 V–2.5 V sensor outputs without level-shifting circuitry. |
| Total Harmonic Distortion | 0.01% at 10 kHz - meets audio-grade signal integrity requirements in differential driver applications with 600 Ω loads. |
Pinout & Package
LMC6035ITLX/NOPB is packaged in an 8-bump DSBGA (YAF0008) using micro SMD technology, measuring 1.5 mm × 1.5 mm × 0.55 mm (bump-side-down mounting). Thermal resistance is RθJA = 103.1°C/W, RθJB = 35.4°C/W, supporting compact, thermally constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | OUT A | Output channel A - drives external load; rail-to-rail swing capability enables full utilization of 2.7 V supply headroom. |
| A1 | OUT B | Output channel B - independent output for dual-path signal conditioning; crosstalk >130 dB at 1 kHz minimizes inter-channel interference. |
| C2 | –IN A | Inverting input channel A - high-impedance node (20 fA bias) suitable for precision integrators and transimpedance amplifiers. |
| A2 | –IN B | Inverting input channel B - electrically isolated from channel A; supports dual-sensor differential measurement topologies. |
| C3 | +IN A | Noninverting input channel A - accepts signals from 0 V to 2.3 V common-mode range at 2.7 V supply without phase reversal. |
| A3 | +IN B | Noninverting input channel B - identical CMVR specification as +IN A; enables matched dual-channel sensor interface design. |
| B3 | V– | Negative supply terminal - tied to ground in single-supply mode; must be decoupled with 0.1 µF ceramic capacitor near package. |
| B1 | V+ | Positive supply terminal - accepts 2.0–15.5 V; quiescent current 0.65–1.6 mA per amplifier enables multi-day battery life in portable devices. |
Key Features
| Feature | Design Value |
|---|---|
| Femtoampere input bias current | 20 fA typical - reduces DC offset drift in high-Z pH electrodes and piezoelectric sensor buffers by >100× vs pA-class op amps. |
| Rail-to-rail output into 600 Ω | 200 mV from rails at 2.7 V - eliminates need for level-shifting in 3 V audio transformer drivers and telecom line interfaces. |
| Ultra-low power consumption | 0.65 mA quiescent current per amplifier at 2.7 V - extends runtime in coin-cell-powered medical wearables beyond 12 months. |
| Wide supply voltage range | 2.0 V to 15.5 V - accommodates both single-cell Li-ion (3.0–4.2 V) and triple-cell NiMH (2.7–4.5 V) battery systems without redesign. |
| High open-loop gain stability | 126 dB gain maintained at 600 Ω load - prevents THD degradation in active filter stages where gain collapse increases harmonic distortion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6042IMX/NOPB | Higher IQ (1.2 mA vs 0.65 mA), wider GBW (2.5 MHz), same DSBGA-8 package and 20 fA IB. | Better for higher-frequency active filters (>500 kHz), less suitable for multi-year battery life targets. | Select LMC6042IMX/NOPB only if bandwidth >1.4 MHz is required; otherwise LMC6035ITLX/NOPB offers superior energy efficiency. |
| TLV2462IDR | Higher IB (1 pA vs 20 fA), lower VOS (±0.5 mV vs ±5 mV), SOIC-8 package, no DSBGA option. | Preferred for precision DC-coupled instrumentation where offset dominates; unsuitable for ultra-high-Z sensor nodes. | Choose TLV2462IDR for offset-critical applications with board space for SOIC; retain LMC6035ITLX/NOPB for space-constrained, high-impedance designs. |
Compared with LMC6042IMX/NOPB and TLV2462IDR, LMC6035ITLX/NOPB uniquely balances femtoampere input leakage, DSBGA-8 footprint, and sub-1 mA quiescent current - making it the only dual op amp qualified for long-life, miniaturized medical and portable instrumentation where both size and leakage are co-constrained.

FAQ
What is the maximum capacitive load the LMC6035ITLX/NOPB can drive without oscillation?
The LMC6035ITLX/NOPB can drive up to 100 pF capacitive load in unity-gain follower configuration when compensated with a 50–100 Ω series resistor at the output and a 5–10 pF feedback capacitor from inverting input to output, as documented in TI Application Note AN-1112. Uncompensated, oscillation may occur above ~30 pF.
Does the LMC6035ITLX/NOPB support true single-supply operation down to 2.0 V?
Yes, the LMC6035ITLX/NOPB is fully specified for operation from 2.0 V to 15.5 V single supply. At 2.0 V, it maintains functional rail-to-rail output swing (within 300 mV of rails at 600 Ω) and usable open-loop gain (>50 dB), though parameters like GBW and slew rate scale downward per the datasheet's "behavior below 2.7 V" characterization.
Is the LMC6035ITLX/NOPB pin-compatible with other LMC603x variants in DSBGA packages?
Yes, the LMC6035ITLX/NOPB shares identical pinout (YAF/YZR) and bump map with all LMC6035 DSBGA variants (e.g., LMC6035YAF, LMC6035YZR). Pin functions - including OUT A (C1), OUT B (A1), –IN A (C2), –IN B (A2), +IN A (C3), +IN B (A3), V– (B3), and V+ (B1) - are electrically and mechanically identical across YAF/YZR suffixes.
What is the thermal performance of the LMC6035ITLX/NOPB in its DSBGA package?
The LMC6035ITLX/NOPB in YAF DSBGA has RθJA = 103.1°C/W and RθJB = 35.4°C/W. With 1.6 mA total quiescent current (0.8 mA per amplifier) at 2.7 V, self-heating is limited to <1.5°C above ambient on standard 2-layer FR-4 - enabling reliable operation in sealed medical enclosures without forced airflow.
Can the LMC6035ITLX/NOPB be used in AEC-Q100 automotive applications?
No - the LMC6035ITLX/NOPB is not AEC-Q100 qualified. For automotive-grade operation, Texas Instruments offers the LMC6035-Q1 variant, which is AEC-Q100 Grade 3 qualified (–40°C to +85°C) and undergoes additional stress testing. The LMC6035ITLX/NOPB is intended for industrial, medical, and portable consumer applications.
