AD8075:  500 MHz, G=+1 and +2 Triple Video Buffers with Disable

Product Details

The AD8074 /AD8075 are high-speed triple video buffers with a G = +1 and +2 respectively. They operate on ±5V and have a -3dB full signal bandwidth in excess of 500MHz, along with slew rates in excess of 1350V/µs. With better than -80dB of all hostile crosstalk and 90dB isolation, they are useful in many high-speed applications. The differential gain and differential phase error are 0.01% and 0.01°. Gain Flatness of 0.1dB up to 70MHz make the AD8074/75 ideal for RGB buffering or driving. They consume less than 30mA on a ±5V supply voltage.

Both devices offer a high-speed disable feature that allows the outputs to be put into a high impedance state. This allows the building of larger input arrays while minimizing "OFF" channel output loading. The AD8074/75 are offered in a 16 lead TSSOP package.

AN-417: Fast Rail-to-Rail Operational Amplifiers Ease Design Constraints in Low Voltage High Speed Systems  (pdf, 228 kB)
Movement towards lower power supply voltages is driven by the demand that systems consume less and less power coupled with the desire to reduce the number of power supply voltages in the system. The following applications are discussed: Single-Ended and Differential Input ADC Input Circuits, Video Line Driver, Active Filter, HDSL Transceiver, and Transformer Drive Circuits.
