Dual Pre-trimmed Blackmer Voltage Controlled Amplifier THAT 2162 FEATURES APPLICATIONS Two Independent Channels Faders Wide Dynamic Range: >118 dB Panners Wide Gain Range: >130 dB Compressors & Limiters Exponential (dB) Gain Control Low Distortion: 0.05% typ. Gates & Expanders Wide Supply Voltage Range: Mixers 2.25V ~ 16V Low Supply Current: 5.2 mA typ. (15V) Equalizers 3 mA typ. (5V) Dual Control Ports (pos/neg) Filters Low Cost Oscillators Small Package (16-pin QSOP) Description THAT 2162 contains two high-performance The 2162 operates from a split power supply Blackmer voltage-controlled amplifiers (VCAs). up to 16 Vdc, drawing only 5.2mA at 15V and With two opposing-polarity, voltage-sensitive 3 mA at 5V. The part can also operate at supply control ports, they offer wide-range exponential voltages as low as 2.25V, making it suitable for control of gain and attenuation with low signal battery-operated applications. distortion. Both VCAs are trimmed at wafer stage The two VCAs are independent of each other, to deliver low distortion and control-voltage sharing only their power supply connections. feedthrough without further adjustment. The 2162 is extremely flexible and capable of However, external symmetry adjustment is possi- being configured for a wide range of stereo or ble to further optimize distortion and control multichannel applications. It is available in a feedthrough for critical applications. RoHS-compliant 16-pin QSOP package.

Sustained operation at or near the Absolute Maximum Ratings conditions is not recommended. In particular, like all semiconductor devices, device reliability declines as operating temperat ure increases. 3 Unless otherwise noted, TA=25C, VCC=+15V, VEE= -15V. 4 Reference is to output offset with -40 dB VCA gain.
