GENERAL DESCRIPTION
The SSM2024 is a quad Class A noninverting current-controlled
transconductance amplifier. Each of the four VCAs is completely independent and includes a ground referenced linear current gain control. These voltage-in/current-out amplifiers offer
over 82 dB S/N at 0.3% THD. Other features include low control voltage feedthrough and minimal external components for
most applications. With four matched VCAs in a single IC, the
SSM2024 provides a convenient solution for applications requiring multiple amplifiers. The pinout groups the four outputs
for easy signal summing for circuits such as four-channel mixers.
