The AD8074/AD8075 are high-speed triple video buffers with G=+1 and +2 gain respectively. They have a -3 dB full signal bandwidth of 600 MHz (200 mV p-p) and 500 MHz (2 V p-p), 1600 V/µs slew rate, 4 ns fast settling time and <30 mA low supply current. They also feature excellent video specifications (RL = 150 Ω): 0.1 dB to 50 MHz gain flatness, 0.01% differential gain error and 0.01° differential phase error. “All hostile” crosstalk is -80 dB@10 MHz and -50 dB@100 MHz. They have high “OFF” isolation (90 dB@10 MHz) and a low cost fast output disable feature.
The AD8074 and AD8075 are high‑speed triple video buffers offering G = +1 and G = +2 configurations. They provide up to 600 MHz small‑signal bandwidth, 1600 V/µs slew rate (AD8074) and 1350 V/µs (AD8075), and a fast 4 ns settling time. Features include low supply current (<30 mA), excellent video specifications such as 0.1 dB gain flatness to 50 MHz, 0.01 % differential gain error, and high‑off isolation of 90 dB.
These devices are intended for RGB buffering and driver applications in LCD and plasma displays. They are supplied in a 16‑lead TSSOP package and include a high‑speed output‑disable function that places outputs in a high‑impedance state, enabling larger input arrays with reduced loading.
| Supply Current | <30 mA |
|---|---|
| Gain Flatness | 0.1 dB to 50 MHz |
| All‑Hostile Crosstalk | -80 dB @ 10 MHz |
| OFF Isolation | 90 dB @ 10 MHz |
| Operating Temperature Range | -40 °C to +85 °C |
| Package | 16‑lead TSSOP |
The devices draw less than 30 mA from a +5 V supply.
It allows the outputs to be placed in a high‑impedance state, reducing loading when building larger input arrays.
They are supplied in a 16‑lead TSSOP package.
They operate from –40 °C to +85 °C in still air.
