Product details
Overview
LMP7701MAX/NOPB from Texas Instruments is a single-channel, precision CMOS-input, rail-to-rail input/output operational amplifier optimized for high-impedance sensor interface and low-voltage instrumentation. It delivers ±200 µV max input offset voltage, ±200 fA input bias current, 2.5 MHz unity-gain bandwidth, and operates from 2.7 V to 12 V supply rails - enabling accurate signal conditioning in battery-powered medical sensors and portable test equipment.
For engineers reviewing the LMP7701MAX/NOPB datasheet, LMP7701MAX/NOPB pinout, LMP7701MAX/NOPB application, or LMP7701MAX/NOPB equivalent, key selection criteria include ultra-low input bias current for photodiode/strain gauge front-ends, rail-to-rail output swing within 40 mV of rails at 3 V supply, and guaranteed performance across −40°C to +125°C industrial temperature range.
Technical Context
The LMP7701MAX/NOPB uses VIP50 CMOS process technology to achieve simultaneous rail-to-rail input common-mode range (−0.2 V to VS + 0.2 V) and wide 2.7–12 V supply operation - a capability not supported by standard CMOS op-amps. Its complementary input stage is laser-trimmed to minimize CMRR glitches near supply rails.
It features 130 dB open-loop gain, 130 dB CMRR, and 9 nV/√Hz input voltage noise at 1 kHz, with output capable of sourcing/sinking ±42 mA (RL = 2 kΩ) while maintaining rail-to-rail swing - making it suitable for driving DAC buffers and active filter stages without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±200 µV max - ensures ≤0.2 mV error in 10 V full-scale 16-bit systems without trimming |
| Input Bias Current | ±200 fA typical - enables stable DC coupling with >10 GΩ source impedances (e.g., pH electrodes) |
| Supply Voltage Range | 2.7 V to 12 V - supports direct operation from single Li-ion (3.0–4.2 V), dual AA (3 V), or 5/12 V rails |
| Unity-Gain Bandwidth | 2.5 MHz - sufficient for anti-aliasing filters up to ~200 kHz and fast-settling DAC buffers |
| Output Swing (3 V) | Within 40 mV of both rails - preserves >93% dynamic range in low-voltage 3 V systems |
| CMRR | 130 dB min - rejects >3.16 MV/V common-mode interference in noisy industrial environments |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control applications |
Pinout & Package
Package: 8-pin SOIC (D package), body size 3.91 mm × 4.90 mm, surface-mount, RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output | Amplifier output node; drives loads up to ±42 mA into 2 kΩ, rail-to-rail swing |
| 2 | Inverting Input (−IN) | Differential input terminal; accepts common-mode voltages from −0.2 V to VS + 0.2 V |
| 3 | Noninverting Input (+IN) | Differential input terminal; matched offset/CMRR trim with Pin 2 for precision DC gain |
| 4 | V− (Negative Supply) | Ground or negative rail connection; required for dual-supply (±5 V) or single-supply (0 V reference) operation |
| 5 | N/C | No internal connection; electrically isolated - may be left floating or tied to ground for mechanical stability |
| 6 | N/C | No internal connection; electrically isolated - no routing or thermal impact required |
| 7 | V+ (Positive Supply) | Primary power input; supports 2.7–12 V range with 715 µA quiescent current at 5 V |
| 8 | N/C | No internal connection; electrically isolated - unused pad; no thermal or EMI implications |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3 V supply range: input accepts signals from −0.2 V to VS + 0.2 V; output swings to within 40 mV of either rail |
| Ultra-low input bias current | ±200 fA typical allows direct interfacing with high-impedance sources (e.g., piezoelectric sensors, glass electrodes) without guard rings or leakage compensation |
| Laser-trimmed input stage | Reduces NMOS/PMOS offset mismatch, delivering 130 dB CMRR even near supply rails - critical for precision differential sensing |
| VIP50 CMOS process | Combines CMOS input advantages (low IB, high ZIN) with extended 12 V supply tolerance - unlike conventional CMOS op-amps limited to ≤5.5 V |
| −40°C to +125°C operation | Guaranteed parametric performance over full industrial temperature range - validated per JEDEC JESD22-A104 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Lower offset (±10 µV typ), but higher supply current (17 µA vs 715 µA); same 2.7–5.5 V range; no 12 V support | Better for ultra-low-offset DC apps below 5.5 V; unsuitable for 9/12 V industrial rails or high-Z sensors requiring sub-pA IB | Select OPA333AIDBVR only when offset dominates design and supply voltage ≤5.5 V; avoid for 12 V or >1 GΩ source impedance |
| ADA4522-1ARMZ | Zero-drift architecture; ±0.3 µV offset, ±20 pA IB, 3 MHz GBW; requires ≥4.5 V supply; higher cost | Superior long-term DC stability for metrology; incompatible with 3 V battery operation due to 4.5 V min supply | Choose ADA4522-1ARMZ for lab-grade accuracy where drift matters more than supply flexibility or cost |
Compared with OPA333AIDBVR and ADA4522-1ARMZ, the LMP7701MAX/NOPB uniquely balances ultra-low input bias current, 12 V supply capability, and industrial temperature rating - making it the only option among the three viable for high-impedance sensor interfaces operating from 3 V to 12 V across −40°C to +125°C.

FAQ
What is the maximum supply voltage rating for the LMP7701MAX/NOPB?
The LMP7701MAX/NOPB has an absolute maximum supply voltage (V+ − V−) of 13.2 V, with recommended operating range from 2.7 V to 12 V. Operation at 12 V is fully characterized across −40°C to +125°C and supports rail-to-rail input/output functionality without derating. Exceeding 13.2 V risks permanent damage per TI's Absolute Maximum Ratings table.
Does the LMP7701MAX/NOPB support true rail-to-rail input with common-mode voltage beyond the supply rails?
Yes - the LMP7701MAX/NOPB supports common-mode input voltage from −0.2 V to VS + 0.2 V, verified across 3 V, 5 V, and ±5 V supplies. This extends 200 mV beyond each rail, enabling robust operation with inputs slightly below ground or above V+, critical for fault-tolerant sensor interfaces and level-shifting circuits.
What is the output drive capability of the LMP7701MAX/NOPB into a 2 kΩ load?
The LMP7701MAX/NOPB delivers ±42 mA output current into a 2 kΩ load at 5 V supply, with output swing maintained within 60 mV of each rail. At 3 V supply, output swing remains within 80 mV of rails under same conditions. This drive strength supports direct interfacing with medium-impedance loads without external buffers.
How does the LMP7701MAX/NOPB achieve low CMRR degradation near supply rails?
The LMP7701MAX/NOPB uses a laser-trimmed complementary CMOS input stage where both NMOS and PMOS differential pairs are actively trimmed to match offsets. This eliminates the typical CMRR "glitch" seen in rail-to-rail input op-amps, ensuring 130 dB minimum CMRR is maintained across the full common-mode range including near V− and V+.
Is the LMP7701MAX/NOPB pin-compatible with other devices in the LMP770x family?
No - the LMP7701MAX/NOPB (8-pin SOIC) is not pin-compatible with LMP7702 or LMP7704. While all share functional similarity, LMP7701 has dedicated IN+, IN−, OUT, V+, and V− pins with three NC pins; LMP7702/LMP7704 use different pinouts for dual/quad configurations. PCB layout must be specific to LMP7701MAX/NOPB.
