NEW!!! SC-1
Mic Preamp Kit
The
SC-1 Mic Preamp is a THAT 1510/1512/SSM2017/SSM2019/INA217
based Mic preamp with phantom power,
DC servo and Balanced line output
driver.
Rev.4
PCB Design for the SC-1 Preamp.
Introduction
The
THAT 1510 is a high performance audio
preamplifier suitable for use in
microphone preamp application. It
is pin compatible with the now discontinued,
Analog Devices SSM2019 and SSM2017
IC chips, and the Texas Instruments
INA217 and INA163 mic preamp chips.
Designed
from the ground up in THAT’s
complementary dielectric isolation
process and including laser-trimmed
Si-Chrome thin film resistors,
the THAT 1510 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 THAT 1510 provide
superior performance in a popular
format at an affordable price.

Goals
The goal is to provide a great performing and nice sounding
mic preamp that's reasonable or cheaper in cost compared
to commercial ready-made, preamp units.
It
will be in kit form. This gives the user the
chance to build the preamp themselves and use their imagination
and creativity in housing this preamp in it's own custom
case.
