FEATURES
117 dB dynamic range 0.006% typical THD+N (@ 1 kHz, unity gain) 140 dB gain range No external trimming required Differential inputs Complementary gain outputs Buffered control port I–V converter on-chip Low external parts count Low cost GENERAL DESCRIPTION
Due to careful gain core layout, the SSM2018 combines the low noise of Class AB topologies with the low distortion of Class A circuits to offer an unprecedented level of sonic transparency. Trimless Voltage Controlled Amplifier SSM2018 FUNCTIONAL BLOCK DIAGRAM SSM2018 VC G +IN GAIN CORE –IN 1–G VG –IG V1–G –I1–G Figure 1. Additional features include differential inputs, a 140 dB (−100 dB to +40 dB) gain range, and a high impedance control port. The SSM2018 provides an internal current-to-voltage converter. Thus, no external active components are required. This device is offered in 16-lead, plastic DIP package and guaranteed for operation over the extended industrial temperature range of −40°C to +85°C.
