说明

The THS4011 and THS4012 are high-speed, single/dual, voltage feedback amplifiers ideal for a wide range of applications. The devices offer good ac performance, with 290-MHz bandwidth, 310-V/µs slew rate, and 37-ns settling time (0.1%). These amplifiers have a high output drive capability of 110 mA and draw only 7.8-mA supply current per channel. For applications requiring low distortion, the THS4011/4012 operate with a total harmonic distortion (THD) of -80 dBc at f = 1 MHz. For video applications, the THS4011/4012 offer 0.1-dB gain flatness to 70 MHz, 0.006% differential gain error, and 0.01° differential phase error.
