Product details
Overview
LMC6035ITL/NOPB from Texas Instruments is a dual-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 active filters.
For engineers reviewing the LMC6035ITL/NOPB datasheet, LMC6035ITL/NOPB pinout, LMC6035ITL/NOPB application, or LMC6035ITL/NOPB equivalent, key selection considerations include its DSBGA-8 (YAF/YZR) package footprint, 2.7V minimum supply compatibility with NiMH/NiCd battery end-of-life voltage, femtoampere input leakage for high-Z sensor interfaces, and verified 0.01% THD at 10 kHz under 2kΩ load.
Technical Context
The LMC6035ITL/NOPB integrates two independent CMOS op amp channels in an 8-bump DSBGA package, each with complementary PMOS/NMOS output stages enabling rail-to-rail swing down to 200 mV from either rail at 2.7 V/600 Ω. Its input stage uses p-channel JFET-like gate structures to achieve 20 fA typical input bias current and >10 TΩ input resistance.
It operates across –40°C to +85°C junction temperature, supports single-supply configurations from 2.0 V to 15.5 V, and maintains specified performance at 2.7 V, 3 V, 5 V, and 15 V supplies - with common-mode input range extending from –0.1 V to +2.3 V at 2.7 V supply, and CMRR ≥ 60 dB over full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 15.5 V single supply - supports direct interface with 2-cell NiMH/NiCd (2.4 V nominal, 2.1 V end-of-life) and 3.3 V/5 V logic systems. |
| Input Bias Current | 20 fA typical at 25°C - enables use of MΩ-range feedback resistors and nF-range capacitors in low-power active filters without DC error accumulation. |
| Rail-to-Rail Output Swing | 200 mV from rails at 2.7 V/600 Ω - delivers >92% supply utilization in space-constrained battery-powered signal chains. |
| Open-Loop Gain | 126 dB typical - ensures <10 µV output error for unity-gain buffer applications with 1 V input, critical for precision sensor front-ends. |
| THD + Noise | 0.01% at 10 kHz, 2 kΩ load - meets audio-grade distortion requirements in differential driver and communication interface circuits. |
| Gain Bandwidth Product | 1.4 MHz - supports stable closed-loop operation up to ~100 kHz with moderate gain (e.g., 10×), suitable for anti-aliasing and reconstruction filters. |
| Quiescent Current | 0.65–1.6 mA per amplifier - enables dual-op-amp functionality in sub-3 mA total system power budgets for portable devices. |
Pinout & Package
LMC6035ITL/NOPB is packaged in an 8-bump DSBGA (chip-scale) package, measuring 1.5 mm × 1.5 mm × 0.55 mm (YAF/YZR variant), with solder bumps on bottom side and no exposed pad. This micro SMD footprint minimizes PCB area and parasitic capacitance for high-impedance node routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | OUT A | Output of channel A - drives external load or next-stage input; rail-to-rail capable with 4–8 mA short-circuit current. |
| C2 | –IN A | Inverting input of channel A - high-impedance node (≥10 TΩ); sensitive to layout-induced leakage; requires guard ring in PCB design. |
| C3 | +IN A | Noninverting input of channel A - same impedance as –IN A; used for unity-gain buffer or high-Z sensor interface. |
| A1 | OUT B | Output of channel B - electrically isolated from OUT A; supports dual-path signal conditioning without crosstalk (>130 dB at 1 kHz). |
| A2 | –IN B | Inverting input of channel B - independent high-Z input; enables dual-channel instrumentation amplifier or differential receiver topologies. |
| A3 | +IN B | Noninverting input of channel B - matches +IN A in electrical characteristics; allows matched dual-channel gain blocks. |
| B3 | V– | Negative supply terminal - connected to ground in single-supply mode; must be decoupled with 100 nF ceramic capacitor near package. |
| B1 | V+ | Positive supply terminal - accepts 2.0–15.5 V; supplies both amplifiers; shared rail enables compact dual-amplifier designs. |
Key Features
| Feature | Design Value |
|---|---|
| Femtoampere input bias current | 20 fA typical - preserves signal integrity from ultra-high-impedance sources (e.g., pH electrodes, piezoelectric sensors, photodiode transimpedance nodes). |
| Rail-to-rail output into 600 Ω | 200 mV from rails at 2.7 V - eliminates need for level-shifting circuitry in low-voltage audio and telecom line drivers. |
| Specified 2.7 V operation | Guaranteed performance at 2.7 V supply - aligns with 3× NiMH/NiCd battery end-of-life (0.9 V/cell), extending usable runtime in portable equipment. |
| Wide common-mode input range | –0.1 V to +2.3 V at 2.7 V - accepts inputs below ground and up to 85% of V+, enabling single-supply difference amplifiers without input clamping. |
| Low THD at 10 kHz | 0.01% with 2 kΩ load - satisfies EN 61000-4-3 immunity testing and audio codec linearity requirements in medical and consumer devices. |

| Differential Audio Driver | Battery-Powered Instrumentation |

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 |
|---|---|---|---|
| LMC6042IMX/NOPB | Higher quiescent current (2.7 mA/ch), wider supply range (1.8–16 V), but larger SOIC-8 package and 100 fA input bias. | Better for 1.8 V logic compatibility and higher-speed applications (3 MHz GBW), less suitable for ultra-low-leakage sensor buffering. | Select when 1.8 V operation or higher slew rate (2.5 V/µs) is required; avoid where femtoampere leakage is mandatory. |
| TLV2462IDR | Lower input bias (1 pA), lower cost, but only 2.7–6 V supply range and 600 mV rail margin at 2.7 V/600 Ω. | Optimized for 3.3 V systems with moderate load drive; insufficient rail margin for 2.7 V battery-critical applications. | Choose for cost-sensitive 3.3 V designs with >100 kΩ loads; not recommended for 2.7 V/600 Ω rail-to-rail output requirements. |
Compared with LMC6035ITL/NOPB, LMC6042IMX/NOPB trades femtoampere input leakage for broader voltage support and speed, while TLV2462IDR offers lower cost and picoampere bias but sacrifices low-voltage rail-to-rail capability - making LMC6035ITL/NOPB uniquely suited for battery-end-of-life operation with ultra-high-impedance sources.

FAQ
What is the maximum supply voltage rating for LMC6035ITL/NOPB?
The absolute maximum supply voltage (V+ – V–) for LMC6035ITL/NOPB is 16 V, but the recommended operating range is 2.0 V to 15.5 V. Operation at 15.5 V is fully characterized per datasheet specifications, including output swing, THD, and open-loop gain - ensuring reliable performance in industrial and telecom line-powered systems.
Does LMC6035ITL/NOPB support true rail-to-rail input common-mode range?
LMC6035ITL/NOPB does not support rail-to-rail input common-mode range. At 2.7 V supply, its specified common-mode input range is –0.1 V to +2.3 V - meaning it accepts inputs 100 mV below ground and up to 400 mV below V+. This exceeds most CMOS op amps at low voltage and enables single-supply difference amplifier configurations without external level shifting.
Can LMC6035ITL/NOPB drive capacitive loads directly?
LMC6035ITL/NOPB is not inherently stable with large capacitive loads (>100 pF) without compensation. The datasheet 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. This is essential for driving ADC input capacitors or long PCB traces in portable instrumentation.
Is LMC6035ITL/NOPB qualified for automotive applications?
LMC6035ITL/NOPB is not automotive-qualified. However, the pin-compatible LMC6035-Q1 variant is AEC-Q100 Grade 3 qualified (–40°C to +85°C) and shares identical electrical specifications. For automotive body electronics or infotainment subsystems requiring qualification, LMC6035-Q1 must be selected instead of LMC6035ITL/NOPB.
What thermal resistance values apply to LMC6035ITL/NOPB in YAF package?
For LMC6035ITL/NOPB in YAF (DSBGA-8) package, the junction-to-ambient thermal resistance (RθJA) is 103.1 °C/W, junction-to-board (RθJB) is 35.4 °C/W, and junction-to-case (top) is 0.5 °C/W. These values assume JEDEC-standard PCB layout with 2 oz copper and 1 in² copper pour - critical for thermal design in sealed portable enclosures.
