Description
The THAT 1510 and 1512 are high perform-
ance audio preamplifiers suitable for microphone
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 potenti-
ometer. The 1510 gain equation is identical to
that of the SSM 2019, reaching 6 dB gain with a
10 kΩ resistor. The 1512 reaches 0 dB gain with
a 10 kΩ resistor. Because the 1512 exhibits
significantly lower noise at lower gain settings, it
is recommended over the 1510 for new designs.
Designed from the ground up in THAT’s
complementary dielectric isolation process and
including laser-trimmed Si-Chrome thin film
resistors, the THAT 1510 and 1512 improve on
existing integrated microphone preamps by offer-
ing 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 THAT 1510 and 1512 provide
superior performance in a popular format at an
affordable price.
