The LTC1150 is a high‑voltage, chopper‑stabilized operational amplifier that integrates the sample‑and‑hold capacitors normally required externally. It operates from a single supply of 4.75 V to 36 V and delivers ultra‑low offset voltage and noise performance.
Key features include a typical supply current of 0.8 mA, offset voltage of 0.5 pV, gain bandwidth product of 2.5 MHz, and slew rate of 3 V/µs. The device is offered in various 8‑lead packages and is suited for strain‑gauge amplifiers, medical instrumentation, thermocouple amplifiers, and high‑resolution data‑acquisition systems.
| Supply Voltage Range | 4.75 V to 36 V |
|---|---|
| Supply Current (No Load) | 0.8 mA |
| Input Offset Voltage | 0.5 pV |
| Gain Bandwidth Product | 2.5 MHz |
| Input Noise Voltage (0.1‑10 Hz) | 1.8 nV p‑p |
Supply current can be programmed through pin 1; leaving it open defaults to 0.8 mA, while tying it to ground or adding a resistor adjusts the current.
Positive saturation recovers in about 20 ms, and negative saturation recovers in about 3 ms.
