Brief Description

The AD707 is a low-cost, high-precision op amp suitable for a wide range of precision applications. It offers state-of-the-art performance with a best-in-class offset voltage spec of less than 15 µV. The AD707's open-loop gain is 8 V/µV minimum, and it has a maximum input voltage noise of 350 nV p-p (0.1 Hz to 10 Hz). It is available in various versions specified for commercial, industrial, and military temperature ranges.

Specifications and Features

Some of the key specifications and features of the AD707 include:

• Very high DC precision
• 15 mV max offset voltage
• 0.1 mV/°C max offset voltage drift
• 0.35 mV p-p max voltage noise (0.1 Hz to 10 Hz)
• 8 V/mV min open-loop gain
• 130 dB min CMRR (Common Mode Rejection Ratio)
• 120 dB min PSRR (Power Supply Rejection Ratio)
• 1 nA max input bias current
• 0.3 V/µs slew rate
• 0.9 MHz closed-loop bandwidth

Application Scenarios

The AD707 is particularly suitable for the following application scenarios:

1. Precision instrumentation applications, thanks to its 13 V/µV typical open-loop gain and 140 dB typical common-mode rejection ratio.
2. Enables tighter error budgets at a lower cost due to its precision.
3. Allows amplification of very small signals without sacrificing overall system performance, thanks to its low offset voltage drift and low noise characteristics.
4. Can be used as a replacement for LT1001 in applications requiring chopper amplifiers, but without inherent noise and application problems.
