Product Details

The AD8031 (single) is a single supply voltage feedback amplifier that features high speed performance with 80 MHz of small signal bandwidth, 30 V/µs slew rate and 125 ns settling time. This performance is possible while consuming less than 4.0 mW of power from a single +5 V supply. This feature increases the operation time of high speed, battery-powered systems without compromising dynamic performance.

The AD8031 has true single supply capability with rail-to-rail input and output characteristics and is specified for +2.7 V, +5 V, and ±5 V supplies. The input voltage range can extend to 500 mV beyond each rail. The output voltage swings to within 20 mV of each rail providing the maximum output dynamic range.

The AD8031 also offers excellent signal quality for only 800 µA of supply current per amplifier; THD is -62 dBc with a 2 V p-p, 1 MHz output signal, and -86 dBc for a 100 kHz, 4.6 V p-p signal on +5 V supply. The low distortion and fast settling time make it ideal as a buffer to single supply ADCs.

Operating on supplies from +2.7 V to +12 V and dual supplies up to ±6 V, the AD8031 is ideal for a wide range of applications, from battery operated systems with large bandwidth requirements to high speed systems where component density requires lower power dissipation. The AD8031 is available in 8-lead PDIP, 8-lead SOIC_N and 5-lead SOT-23 packages and operates over the industrial temperature range of -40°C to +85°C.

Product Details

This evaluation board is designed to help users evaluate the AD8031. The evaluation board is a bare board: there are no components or amplifiers soldered to the board. These parts must be obtained separately from the table below or on the product page. Free samples may also be requested. The unpopulated board enables users to quickly customize and prototype a variety of op amp circuits, which minimizes risk and reduces time to market.

The User Guide contains all the required documentation to build the board, including schematics, assembly drawing, and Bill of Materials.

Product Details

The SO8 SINGLE AMP evaluation board aids in the evaluation of single, 8-lead SOIC operational amplifiers. The SO8 SINGLE AMP  evaluation board is a bare board with no components soldered on, which enables users to prototype a variety of operational amplifier circuits. The SO8 SINGLE AMP evaluation board supports any of the Analog Devices, Inc., single operational amplifiers in 8-lead SOIC packages with and without a dedicated feedback pin, an exposed paddle, and an external compensation pin.

The 6-layer evaluation board accepts edge mounted SMA connectors on both inputs and outputs to allow an efficient connection to test equipment and other circuitry.

Optimized power and ground planes ensure low noise and high speed operation. Component placement and power supply bypassing are optimized for maximum circuit flexibility and performance. The evaluation board accepts 0402 or 0603 surface-mount technology (SMT) components, 1206 bypass capacitors, and 100 mil headers.

All components are placed on the primary side. No components are placed on the secondary side.
