ADA4099-1 Operational Amplifier

ADI's ADA4099-1 is a robust, precision, rail-to-rail input/output operational amplifier (op amp) with inputs that operate from -V_S to +V_S and beyond. The inputs also tolerate up to 80 V of differential voltage without damage or degradation to DC accuracy. The device features offset voltages of < 25 µV, input bias currents < 4 nA, and can operate from 3.15 V to 50 V

The ADA4099-1 is unity-gain stable and can drive loads requiring up to 20 mA; it can also drive capacitive loads as large as 100 pF. The amplifier is available with low power shutdown. The ADA4099-1 is available in a standard, 6-lead, thin small outline transistor (TSOT) package.

The EVAL-ADA4099-1HUJZ evaluates the ADA4099-1 op amp; it is a prepopulated board using a gain of 1 configuration.

The board’s design allows simplified and efficient use. It has edge-mounted subminiature version A (SMA) connectors on the inputs and outputs to allow efficient connection to test equipment or other circuits. Bulk test points are also incorporated as an alternative option to be used for the inputs and outputs. The optimized EVAL-ADA4099-1HUJZ ground plane, component placement, and power supply allow maximum circuit flexibility and performance. The EVAL-ADA4099-1HUJZ combines surface-mount technology (SMT) with almost all components being 0805 in size to provide simplified installation and the option to replace and solder when needed, except for the bypass capacitors (C1 to C4) that are fixed in 0603 sizes. The EVAL-ADA4099-1HUJZ also has unpopulated resistor and capacitor pads, which provide the user with the options and flexibility to implement different application circuits and configurations.

Features

• Over-The-Top technology provides customers with a robust front-end design and allows signals to be sensed, even if the bias is outside the parts' supply voltage
• Low voltage noise can detect and amplify very small signals that are normally lost within the system noise
• Shutdown option for systems that are power-control optimized, which provides duty-cycling to maintain performance when needed
