Product details
Overview
LM201AN from STMicroelectronics is a single general-purpose operational amplifier with ±5V to ±22V supply range, 0.7mV typical input offset voltage, 25nA typical input bias current, and 10V/µs slew rate in inverting configuration. It operates from –40°C to +105°C and is used in precision analog signal conditioning, sensor interface circuits, and industrial control feedback loops.
For engineers reviewing the LM201AN datasheet, LM201AN pinout, LM201AN application, or LM201AN equivalent, this page provides verified electrical parameters, DIP-8 package layout, temperature-grade context, compensation flexibility, and direct alternatives for design-in and replacement decisions.
Technical Context
The LM201A uses an external 30pF capacitor for single-pole compensation, enabling configurable bandwidth–slew rate trade-offs: 3.5MHz gain-bandwidth product and 10V/µs slew rate are achievable in inverting configurations. Its input stage features differential pair topology with balanced offset trimming.
It includes internal input and output overload protection, no latch-up under common-mode overvoltage, and stable unity-gain operation without oscillation when properly compensated. Input common-mode range extends to ±15V at ±20V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5V to ±22V - supports wide industrial rail options including ±12V and ±15V systems |
| Input Offset Voltage (Typ.) | 0.7mV - enables sub-mV error budgets in DC-coupled transducer amplifiers |
| Input Bias Current (Typ.) | 25nA - low enough for high-impedance sensor interfaces (e.g., pH electrodes, photodiode TIA) |
| Slew Rate (Inverting) | 10V/µs - sufficient for 100kHz full-power sine wave at 10Vpp without distortion |
| Gain-Bandwidth Product | 0.5MHz (min), 1MHz (typ.) - defines closed-loop bandwidth limit at given gain setting |
| Operating Temperature | –40°C to +105°C - qualified for extended industrial environments, not commercial-only |
| Input Common-Mode Range | ±15V at ±20V supply - allows rail-to-rail input handling near supply extremes |
Pinout & Package
LM201AN is supplied in an 8-pin plastic dual in-line package (DIP-8) with standard through-hole mounting footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Balance / Null | Connects to external potentiometer for manual input offset nulling |
| 2 | Inverting Input (–) | Differential input node; high-impedance, sensitive to noise and layout |
| 3 | Non-inverting Input (+) | Differential input node; referenced to common-mode voltage range |
| 4 | VCC– | Negative supply rail connection; must be decoupled locally |
| 5 | Balance / Null | Second null terminal; used with Pin 1 for symmetric offset trim |
| 6 | Output | Class-A/B output stage; capable of ±12V swing into 10kΩ load |
| 7 | VCC+ | Positive supply rail connection; requires local 0.1µF ceramic decoupling |
| 8 | Compensation | External 30pF capacitor connection point for dominant-pole frequency compensation |
Key Features
| Feature | Design Value |
|---|---|
| Externally compensatable | Single 30pF capacitor sets bandwidth/slew rate - avoids fixed internal compensation limitations |
| No latch-up on CM overvoltage | Operates safely even when input exceeds supply rails - simplifies front-end protection design |
| Input/output overload protection | Withstands momentary shorts and overvoltage without damage - improves field reliability |
| Stable at unity gain | No oscillation with proper 30pF compensation - validated for buffer and gain-of-one applications |
| Wide supply range | ±5V to ±22V operation - eliminates need for separate low-voltage op-amps in mixed-rail systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM301AN | 0°C to +70°C temp grade; 2mV max Vio vs. 3mV for LM201AN; same pinout and compensation | Limited to commercial-temperature environments; lower cost but unsuitable for extended industrial use | Select when ambient stays within 0–70°C and offset budget allows ≤2mV |
| LM101AH | –55°C to +125°C grade; metal-can TO-99 package; identical electrical specs except higher Ptot (500mW) | Used in military/aerospace where hermetic sealing and extreme temp range required | Choose only when DIP-8 plastic is insufficient and thermal/mechanical ruggedness is critical |
Compared with LM301AN and LM101AH, the LM201AN uniquely balances industrial temperature range, DIP-8 manufacturability, and proven stability with external compensation-making it optimal for volume industrial designs needing reliability beyond commercial grade but without hermetic cost or form factor constraints.

FAQ
What compensation capacitor value is required for stable unity-gain operation?
A single 30pF capacitor connected between Pin 8 (Compensation) and Pin 4 (VCC–) ensures stable unity-gain operation with 3.5MHz bandwidth and 10V/µs slew rate. Values below 25pF may cause ringing; above 40pF reduces bandwidth unnecessarily. Ceramic C0G/NP0 type is recommended for temperature stability.
Can LM201AN drive a 2kΩ load at ±10V output swing?
Yes - LM201AN delivers ±12V output swing into 10kΩ and ±10V into 2kΩ at ±15V supplies, per datasheet electrical characteristics. Output short-circuit current is rated at 10–50mA, confirming safe operation into 2kΩ loads without thermal shutdown under continuous DC conditions.
Is Pin 1 and Pin 5 both required for offset nulling?
Yes - Pins 1 and 5 form a balanced null port pair. A 10kΩ potentiometer is connected across them with its wiper to VCC– (Pin 4); adjusting the potentiometer nulls input offset voltage. Omitting either pin breaks the symmetry and degrades nulling effectiveness.
Does LM201AN support single-supply operation?
No - LM201AN is designed for dual-supply operation (±5V to ±22V). Its input common-mode and output swing are specified relative to symmetric rails. Single-supply use violates absolute maximum ratings and causes clipping or undefined behavior; dedicated single-supply op-amps like TS912 should be used instead.
