description
The THS6072 is a high-speed, low-power differential receiver designed for ADSL communication systems. Its
low 3.4-mA per channel quiescent current reduces power to half that of other ADSL receivers making it ideal
for low power ADSL applications. This receiver operates with a very low distortion of –79 dBc
(f = 1 MHz, R
L
= 1 kΩ). The THS6072 is a voltage feedback amplifier offering a high 175-MHz bandwidth and
230-V/µs slew rate and is unity gain stable. It operates over a wide range of power supply voltages including
±4.5 V to ±15 V. This device is available in a standard SOIC or MSOP PowerPAD package.
