GENERAL DESCRIPTION Continued
The SSM-2110hasadynamic range of 1OOdS.Auniqueon-chip
prebias circuit enables the users to trade dynamic range at low
signal levels for a faster response time. As a precision level
detector, the SSM-211 0 has applications in digital multimeters.
panel meters, process control and audio systems.
