Description
The THAT 1510 and 1512 are high perfor-
mance audio preamplifiers suitable for micro-
phone preamp and bus summing applications.
The ICs are pin compatible with the Analog De-
vices SSM2017 in both the 8-pin DIP and
16-pin SOIC packages.
The THAT1512 follows a different gain
equation than the 1510, but exhibits signifi-
cantly lower noise at lower gain settings and is
recommended for new designs.
Designed from the ground up in THAT's
complementary bipolar, dielectric isolation
process, the THAT 1510 and 1512 improve on
existing integrated microphone preamps by of-
fering lower noise at low gains, better distor-
tion characteristics, lower power consumption,
higher slew rate and bandwidth, and increased
output voltage swing. The parts are fully pro-
tected against ESD on all critical pins, and reli-
ability is further enhanced by their reduced
power requirements.
In short, the THAT 1510 and 1512 provide
superior performance in a popular format at an
affordable price.
