Low-Noise, High Performance Audio Preamplifier IC THAT 1510, 1512 FEATURES APPLICATIONS Low Noise: Differential Low Noise Preamplifiers 1 nV/Hz input noise (60dB gain) Differential Summing Amplifiers 34 nV/Hz input noise (0dB gain) (1512) Low THD+N (full audio bandwidth): Differential Variable Gain Amplifiers 0.001% 40 dB gain 0.005% 60 dB gain Microphone Preamplifiers Low Current: 6mA typ. Moving-Coil Transducer Amplifiers Wide Bandwidth: 7MHz G=100 High Slew Rate: 19 V/ s Line Input Stages Wide Output Swing: 13.3V on Audio 15V supplies Gain adjustable from 0 to >60 dB with Sonar one external resistor Instrumentation Industry Standard Pinouts Description The THAT 1510 and 1512 are high perform- significantly lower noise at lower gain settings, it ance audio preamplifiers suitable for microphone is recommended over the 1510 for new designs. preamp and bus summing applications. The ICs Designed from the ground up in THATs are available in a variety of packages and pin complementary dielectric isolation process and configurations, making them pin compatible with the Analog Devices SSM2019 and SSM2017 including laser-trimmed Si-Chrome thin film (discontinued), and the Texas Instruments resistors, the THAT 1510 and 1512 improve on INA217 and INA163. existing integrated microphone preamps by offer- ing lower noise at low gains, wider bandwidth, Gain for both parts is adjustable via one higher slew rate, lower distortion, and lower external resistor, making it possible to control supply current. The parts feature internal ESD gain over a wide range with a single-gang potenti- overload protection on all critical pins. ometer. The 1510 gain equation is identical to that of the SSM 2019, reaching 6 dB gain with a In short, the THAT 1510 and 1512 provide 10 k resistor. The 1512 reaches 0 dB gain with superior performance in a popular format at an a 10 k resistor. Because the 1512 exhibits affordable price.
