DESCRIPTION
The THS6062 is a high-speed differential receiver designed for ADSL data communication systems. Its very low
1.6 nV/√Hz voltage noise provides the high signal-to-noise ratios necessary for the long transmission lengths of
ADSL systems over copper telephone lines. In addition, this receiver operates with a very low distortion of –90
dBc (f = 1 MHz, R_L = 1 kΩ), exceeding the distortion requirements of ADSL CODECs. The THS6062 is a voltage
feedback amplifier offering a high 100-MHz bandwidth and 100-V/μs slew rate and is stable at gains of 2(–1) or
greater. It operates over a wide range of power supply voltages including 5 V and ±5 V to ±15 V. This device is
available in standard SOIC or MSOP PowerPAD package. The small, surface-mount, thermally-enhanced MSOP
PowerPAD package is fully compatible with automated surface-mount assembly procedures.
