Product details
Overview
LMC6035IMMX/NOPB from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for low-voltage, single-supply operation (2.0V–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 LMC6035IMMX/NOPB datasheet, LMC6035IMMX/NOPB pinout, LMC6035IMMX/NOPB application, or LMC6035IMMX/NOPB equivalent, key selection criteria include femtoampere-level input leakage, guaranteed 2.7V operation with 200 mV rail margin at 600 Ω, wide common-mode range (–0.1 V to +2.3 V at 2.7 V), THD of 0.01% at 10 kHz, and compatibility with DSBGA-8 (YAF/YZR) and SOIC-8 packages.
Technical Context
The LMC6035IMMX/NOPB implements a complementary CMOS input stage with p-channel and n-channel MOSFETs, enabling ultra-low input current and rail-to-rail common-mode voltage range down to –0.1 V at 2.7 V supply. Its output stage uses a totem-pole configuration with matched channel resistances to sustain rail-to-rail swing under heavy load.
It operates across 2.0 V–15.5 V supply range with specified performance at 2.7 V, 3 V, 5 V, and 15 V, and supports both single-supply (e.g., 2.7 V) and split-supply (±1 V to ±7.75 V) configurations. Gain bandwidth product is 1.4 MHz and slew rate is 1.5 V/µs at 15 V, with phase margin of 48° and gain margin of 17 dB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 15.5 V - supports end-of-life NiCd/NiMH battery voltage (2.7 V) and industrial 15 V rails without redesign. |
| Input Bias Current | 20 fA typical - enables use of >10 MΩ feedback networks and high-value RC filters without DC error accumulation. |
| Rail-to-Rail Output Swing | 200 mV from either rail at 2.7 V / 600 Ω - delivers full dynamic range in low-voltage portable systems. |
| Open-Loop Gain | 126 dB (2000 V/mV) - ensures <0.01% closed-loop gain error with 100 kΩ feedback resistors. |
| Total Harmonic Distortion | 0.01% at 10 kHz - meets audio-grade signal fidelity requirements in active filter and preamplifier stages. |
| Gain Bandwidth Product | 1.4 MHz - supports stable unity-gain buffer and 2-pole active filter designs up to ~100 kHz. |
| Input Common-Mode Range | –0.1 V to +2.3 V at 2.7 V - accepts signals below ground and near positive rail for single-supply sensor interfacing. |
Pinout & Package
LMC6035IMMX/NOPB is packaged in an 8-pin DSBGA (chip-scale) package with bump-side-down orientation (package code YAF/YZR). The device uses micro SMD technology and measures 1.5 mm × 1.5 mm with 0.5 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | OUT A | Output of Channel A - drives external load or next-stage input; rail-to-rail capable. |
| C2 | –IN A | Inverting input of Channel A - connects to feedback network or inverting node of differential circuit. |
| C3 | +IN A | Noninverting input of Channel A - interfaces with high-impedance sensors or reference sources. |
| B3 | V– | Negative supply terminal - tied to ground in single-supply operation; must be stable and low-noise. |
| A3 | +IN B | Noninverting input of Channel B - independent input path for dual-channel signal conditioning. |
| A2 | –IN B | Inverting input of Channel B - used for second feedback loop or differential pair configuration. |
| A1 | OUT B | Output of Channel B - fully independent output with same drive capability as OUT A. |
| B1 | V+ | Positive supply terminal - accepts 2.0–15.5 V; decoupling capacitor required adjacent to pin. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| TLV2462IDR | Higher input bias current (1 pA vs 20 fA); lower GBW (6.4 MHz); no 2.7 V guaranteed spec. | Less suitable for ultra-high-Z sensor buffering but better for higher-speed filtering above 100 kHz. | Select TLV2462IDR when speed >1 MHz and input impedance <1 GΩ suffices. |
| OPA2333AIDR | Zero-drift architecture; lower offset (2 µV vs ±5 mV); higher IQ (17 µA vs 650 µA); 2.7 V min supply. | Better for DC-critical applications like precision weigh scales; less optimal for battery runtime-limited devices. | Select OPA2333AIDR when sub-µV offset and drift dominate over quiescent current. |
Compared with TLV2462IDR and OPA2333AIDR, LMC6035IMMX/NOPB uniquely balances femtoampere input leakage, 2.7 V guaranteed operation, and 650 µA quiescent current - making it the only dual op amp qualified for long-life, high-impedance, single-supply portable instrumentation where both leakage and supply headroom are critical.

FAQ
What is the minimum supply voltage for reliable operation of LMC6035IMMX/NOPB?
The LMC6035IMMX/NOPB is fully specified from 2.0 V to 15.5 V, with guaranteed performance at 2.7 V - corresponding to the end-of-life voltage of three series-connected NiCd/NiMH cells. Operation below 2.7 V is functional but with gradually reduced output swing and open-loop gain; design margin exists down to 2.0 V for emergency or deep-discharge scenarios.
Does LMC6035IMMX/NOPB support true rail-to-rail input common-mode range?
No - the LMC6035IMMX/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. It does not accept inputs all the way to V+ (2.7 V) or below V– (0 V) in single-supply mode. For full rail-to-rail input, consider TI's LMC6482 or OPA2320 families.
Can LMC6035IMMX/NOPB drive capacitive loads without oscillation?
The LMC6035IMMX/NOPB is not inherently unity-gain stable into large capacitive loads. Oscillation risk increases above ~100 pF. Stable operation requires compensation: add a 50–100 Ω series resistor at the output and/or a 5–10 pF feedback capacitor from output to inverting input, as documented in TI Application Note AN-1112 and datasheet Figure 7-1.
What is the thermal resistance (RθJA) of LMC6035IMMX/NOPB in its DSBGA package?
In the YAF/YZR 8-bump DSBGA package, LMC6035IMMX/NOPB has a junction-to-ambient thermal resistance (RθJA) of 93.8 °C/W (YZR) or 103.1 °C/W (YAF), measured on a 2-layer JEDEC-standard board. This enables continuous operation at up to 85°C ambient when dissipating ≤12.8 mW per amplifier (based on 1.6 mA IQ at 2.7 V).
Is LMC6035IMMX/NOPB qualified for automotive applications?
The standard LMC6035IMMX/NOPB is not AEC-Q100 qualified. However, the pin-compatible LMC6035QIMMX/NOPB variant is AEC-Q100 Grade 3 qualified (–40°C to +85°C) and intended for automotive infotainment and body electronics. Use LMC6035QIMMX/NOPB for automotive deployments requiring qualification evidence.
