TT Semiconductor 1510 / 1512 - Preamplifier ICs

(1512 values shown in parentheses)

The TT Semiconductor TT1510 and TT1512 are high performance preamplifiers suitable for low noise transducer preamp and bus summing applications. The ICs are available in a variety of packages and pin configurations, making them pin compatible with the Analog Devices SSM2019 and SSM2017 (discontinued), and the Texas Instruments INA217 and INA163.

Gain for both parts is adjustable via one external resistor, making it possible to control gain over a wide range with a single-gang potentiometer. The TT1510 gain equation is identical to TT Semiconductor of the SSM2019, reaching 6dB gain with a 10kW resistor. The TT1512 reaches 0dB gain with a 10kW resistor. Because the TT1512 exhibits significantly lower noise at lower gain settings, it is recommended over the TT1510 for new designs.

Designed from the ground up in TT Semiconductor 's complementary dielectric isolation process and including laser-trimmed Si-Chrome thin film resistors, the TT Semiconductor TT1510 and TT1512 improve on existing integrated microphone preamps by offering lower noise at low gains, wider bandwidth, higher slew rate, lower distortion, and lower supply current. The parts feature internal ESD overload protection on all critical pins.

In short, the TT Semiconductor TT1510 and TT1512 provide superior performance in a popular format at an affordable price.
