GENERAL DESCRIPTION
The SSM2019 is a latest generation audio preamplifier, combining SSM preamplifier design expertise with advanced processing.
The result is excellent audio performance from a monolithic
device, requiring only one external gain set resistor or potentiometer. The SSM2019 is further enhanced by its unity gain stability.
Key specifications include ultra-low noise (1.5 dB noise figure) and
THD (<0.01% at G = 100), complemented by wide bandwidth
and high slew rate.
Applications for this low cost device include microphone preamplifiers and bus summing amplifiers in professional and consumer
audio equipment, sonar, and other applications requiring a low

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

qJA is specified for worst-case mounting conditions, i.e., qJA is specified for device
in socket for PDIP; qJA is specified for device soldered to printed circuit board for
SOIC package.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the SSM2019 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

The SSM2019 is a very low noise audio preamplifier exhibiting
a typical voltage noise density of only 1 nV/÷Hz at 1 kHz. The
exceptionally low noise characteristics of the SSM2019 are in
part achieved by operating the input transistors at high collector
currents since the voltage noise is inversely proportional to the
square root of the collector current. Current noise, however, is
directly proportional to the square root of the collector current.
As a result, the outstanding voltage noise performance of the
SSM2019 is obtained at the expense of current noise performance.
At low preamplifier gains, the effect of the SSM2019 voltage
and current noise is insignificant.

The total noise of an audio preamplifier channel can be calculated by:
E n = e n 2 + ( i n RS )2 + e t 2
where:
En = total input referred noise
en = amplifier voltage noise
in = amplifier current noise
The voltage gain can range from 1 to 3500. A gain set resistor is
not required for unity gain applications. Metal film or wire-wound
resistors are recommended for best results.
RS = source resistance
et = source resistance thermal noise
The total gain accuracy of the SSM2019 is determined by the
tolerance of the external gain set resistor, RG, combined with the
gain equation accuracy of the SSM2019. Total gain drift combines
the mismatch of the external gain set resistor drift with that of
the internal resistors (20 ppm/∞C typ).
For a microphone preamplifier, using a typical microphone
impedance of 150 W, the total input referred noise is:
Bandwidth of the SSM2019 is relatively independent of gain,
as shown in Figure 2. For a voltage gain of 1000, the SSM2019
has a small-signal bandwidth of 200 kHz. At unity gain, the
bandwidth of the SSM2019 exceeds 4 MHz.

in = 2 pA/÷Hz @ 1 kHz, SSM2019 in
RS = 150 W, microphone source impedance
et = 1.6 nV/÷Hz @ 1 kHz, microphone thermal noise
This total noise is extremely low and makes the SSM2019
virtually transparent to the user.

REV. A
SSM2019
Although the SSM2019 inputs are fully floating, care must be
exercised to ensure that both inputs have a dc bias connection
capable of maintaining them within the input common-mode
range. The usual method of achieving this is to ground one side
of the transducer as in Figure 3a. An alternative way is to float
the transducer and use two resistors to set the bias point as in
Figure 3b. The value of these resistors can be up to 10 kW, but
they should be kept as small as possible to limit common-mode
pickup. Noise contribution by resistors is negligible since it is
attenuated by the transducer’s impedance. Balanced transducers
give the best noise immunity and interface directly as in Figure 3c.
INPUTS
The SSM2019 has protection diodes across the base emitter
junctions of the input transistors. These prevent accidental
avalanche breakdown, which could seriously degrade noise
performance. Additional clamp diodes are also provided to prevent
the inputs from being forced too far beyond the supplies.
(INVERTING)
SSM2019
TRANSDUCER
(NONINVERTING)
For stability, it is required to put an RF bypass capacitor directly
across the inputs, as shown in Figures 3 and 4. This capacitor
should be placed as close as possible to the input terminals. Good
RF practice should also be followed in layout and power supply
bypassing, since the SSM2019 uses very high bandwidth devices.

REFERENCE TERMINAL
SSM2019
The output signal is specified with respect to the reference terminal,
which is normally connected to analog ground. The reference
may also be used for offset correction or level shifting. A reference source resistance will reduce the common-mode rejection
by the ratio of 5 kW/RREF. If the reference source resistance is
1 W, then the CMR will be reduced to 74 dB (5 kW/1 W = 74 dB).
b. Pseudo-Differential
COMMON-MODE REJECTION
Ideally, a microphone preamplifier responds to only the difference
between the two input signals and rejects common-mode voltages
and noise. In practice, there is a small change in output voltage
when both inputs experience the same common-mode voltage
change; the ratio of these voltages is called the common-mode
gain. Common-mode rejection (CMR) is the logarithm of the ratio
of differential-mode gain to common-mode gain, expressed in dB.

scheme of Figure 5. If ac coupling is used throughout, then Pins 2
and 3 may be directly grounded.
BUS SUMMING AMPLIFIER
In addition to its use as a microphone preamplifier, the SSM2019
can be used as a very low noise summing amplifier. Such a circuit
is particularly useful when many medium impedance outputs
are summed together to produce a high effective noise gain.
The principle of the summing amplifier is to ground the SSM2019
inputs. Under these conditions, Pins 1 and 8 are ac virtual grounds
sitting about 0.55 V below ground. To remove the 0.55 V offset,
the circuit of Figure 5 is recommended.

places Pins l and 8 at a true dc virtual ground. R4 in conjunction
with C2 removes the voltage noise of A2, and in fact just about
any operational amplifier will work well here since it is removed
from the signal path. If the dc offset at Pins l and 8 is not too
