Product details
Overview
LM201AH from Texas Instruments is a general-purpose operational amplifier with externally compensated architecture, 10 V/μs slew rate in summing configuration, ≤3 mV max input offset voltage over temperature, ≤100 nA max input bias current over temperature, and −25°C to +85°C operating range. It serves as a precision gain block or integrator core in industrial signal conditioning and analog computing circuits.
For engineers reviewing the LM201AH datasheet, LM201AH pinout, LM201AH application, or LM201AH equivalent, key selection criteria include external compensation flexibility, low input current for high-Z timing circuits, guaranteed offset drift performance, and TO-99 metal-can thermal stability in embedded control loops.
Technical Context
The LM201AH implements a classic bipolar input stage with active biasing to minimize input current drift and enable stable operation across its −25°C to +85°C ambient range. Its open-loop gain exceeds 25 V/mV at ±15 V supply with 2 kΩ load, and it supports feedforward or two-pole compensation topologies for bandwidth optimization.
Input common-mode range extends to ±15 V at ±20 V supply, output swing reaches ±13 V into 2 kΩ, and internal overload protection prevents latch-up when common-mode limits are exceeded. The device requires no internal compensation capacitor, relying instead on user-selected external CS (typically 30 pF) for stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±20 V - supports wide-rail industrial supplies without external regulators |
| Input Offset Voltage (max) | 3 mV over −25°C to +85°C - enables DC-coupled sensor amplification without frequent nulling |
| Input Bias Current (max) | 100 nA over −25°C to +85°C - suitable for >10 MΩ source impedances in integrators and sample-hold |
| Slew Rate | 10 V/μs in summing amplifier configuration - delivers fast transient response for pulse conditioning |
| Large-Signal Voltage Gain | 25 V/mV min at ±15 V, 2 kΩ load - ensures ≥60 dB loop gain for precision closed-loop designs |
| Common-Mode Rejection Ratio | 80 dB min - rejects noise in single-ended sensor interfaces with unbalanced routing |
| Package Thermal Resistance θJA | 110°C/W (TO-99, still air) - allows 500 mW dissipation at 75°C ambient before junction limit |
Pinout & Package
LM201AH is housed in an 8-pin TO-99 metal can package (TI package code LMC0008C), providing superior thermal conduction and EMI shielding for noise-sensitive analog stages. The hermetically sealed case supports long-term reliability in industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null | Connects to potentiometer wiper for manual input offset trimming; required for sub-mV DC accuracy |
| 2 | Inverting Input (−) | Differential input node; high impedance (≥1.5 MΩ) enables direct connection to high-Z sensors |
| 3 | Non-Inverting Input (+) | Differential input node; common-mode range extends to ±15 V at ±20 V supply |
| 4 | V− | Negative supply rail; must be decoupled locally to suppress ground bounce in multi-op-amp systems |
| 5 | Offset Null | Second terminal of nulling potentiometer; forms balanced bridge with Pin 1 for drift compensation |
| 6 | Output | Class-A output stage; drives ≥2 kΩ loads to ±13 V; short-circuit protected for continuous operation |
| 7 | V+ | Positive supply rail; requires low-inductance bypass capacitor (0.1 μF ceramic + 10 μF tantalum) |
| 8 | Compensation | External capacitor connection point (CS); 30 pF typical for unity-gain stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Externally compensated architecture | Enables bandwidth tailoring: overcompensation for stability in low-frequency integrators or optimized CS for >3 MHz small-signal bandwidth |
| No latch-up under common-mode overvoltage | Operates safely even when inputs exceed supply rails - critical for sensor fault tolerance in motor control feedback |
| Input overload protection | Withstands ±30 V differential input without damage - eliminates need for external clamping diodes in ruggedized designs |
| Specified drift characteristics | Average offset drift ≤15 μV/°C and bias current drift ≤0.1 nA/°C - enables predictable calibration intervals in field-deployed equipment |
| Low-noise high-impedance operation | Input noise voltage 18 nV/√Hz at 1 kHz; combined with 100 nA max IB, ideal for photodiode transimpedance amps |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM301AH/NOPB | 0°C to +70°C temp range; 7.5 mV max offset voltage; 50 nA max input offset current | Lower-cost option for commercial-grade instrumentation where extended temperature range is unnecessary | Select LM301AH/NOPB only when ambient stays within 0–70°C and offset budget allows ≥7 mV |
| LM101AH/NOPB | −55°C to +125°C temp range; 2 mV max offset; 10 nA max input offset current; higher price | Military/aerospace use requiring full-spec performance across extreme temperatures | Choose LM101AH/NOPB when design must operate reliably at −55°C or above +105°C |

FAQ
What is the maximum operating temperature range for the LM201AH?
The LM201AH is specified to operate from −25°C to +85°C ambient temperature. This range is confirmed in the Absolute Maximum Ratings table and Electrical Characteristics section of the official TI datasheet SNOSBS0D. Operation outside this range may result in parametric degradation or functional failure. The LM201AH/NOPB variant maintains identical thermal specifications.
Does the LM201AH require an external compensation capacitor, and what value is recommended?
Yes, the LM201AH requires an external compensation capacitor connected between Pin 8 (Compensation) and Pin 4 (V−). A 30 pF capacitor is the standard value for unity-gain stable operation with source resistances below 10 kΩ and stray capacitance under 5 pF. Larger values (e.g., 100–200 pF) are used for overcompensation in low-frequency integrators to improve phase margin.
Can the LM201AH drive capacitive loads directly, or is isolation required?
The LM201AH cannot drive large capacitive loads (>100 pF) directly without risk of instability. Figure 37 in the TI datasheet explicitly recommends adding an RC isolation network (e.g., 100 Ω + 100 pF) between Pin 6 (Output) and the load. This prevents peaking and ringing caused by phase shift introduced by cable or PCB trace capacitance.
What is the purpose of Pins 1 and 5 on the LM201AH, and how are they used?
Pins 1 and 5 are the offset null terminals of the LM201AH. They connect to opposite ends of a 10 kΩ potentiometer (wiper to V−), enabling manual adjustment of input offset voltage to ≤0.5 mV. This nulling is essential in DC-coupled applications like precision integrators or sensor amplifiers where residual offset would integrate into significant error over time.
Is the LM201AH pin-compatible with the LM301AH or LM101AH?
Yes, the LM201AH is pin-compatible with both the LM301AH and LM101AH in the TO-99 (LMC0008C) package - all share identical 8-pin layout, pin functions, and mechanical footprint. However, electrical specifications differ: LM101AH supports −55°C to +125°C, LM301AH is rated 0°C to +70°C, and LM201AH covers −25°C to +85°C with intermediate offset and bias current limits.
