MHz No phase reversal Low input currents:. The tone bursts range from 66 dbv 0. Also, please note the warehouse location for the product ordered.

Models for the following parts are available in LTspice: At power-up, this rrmz. Universal Changes to Ordering Guide The gain control of the VCA is logarithmic a linear change in control signal causes a db change in gain.

Low Voltage Microphone Preamplifier with Variable Compression and Noise Gating SSM2167

The rotation point for the SSM is set internally to 24 dbv 63 mv rms. This effect is shown in Figure 7. Once an order has been placed, Analog Devices, Inc. Designed primarily for voice-band applications, this integrated circuit provides amplification, limiting, variable compression, and noise gate.

View Detailed Evaluation Kit Information. The SSM also features a low power shutdown mode for battery-powered applications.

  JASPERETL TUTORIAL PDF

For power-on to shutdown, the SSM requires more time, typically less than sec. Please consult the datasheet for more information. Specifications subject to change without notice.

The SSM shutdown current is related to both temperature and voltage. Didn’t find what you were looking for? A low noise voltage controlled amplifier VCA provides a gain that is dynamically adjusted by a control loop to maintain a set compression characteristic.

Access the user guide UG To make this website work, we log user data and share it with processors.

The quiescent current is as low as More information. G Page of 2. The regulator delivers up to 1A from More information.

Sample availability may be better than production availability. The following applications hints should be considered for the PCB. The bias supply drives More information.

The various ranges specified are as follows:. Brett Horn 1 years ago Views: In Figure 3 and Figure 4, the input signal to the SSM not shown is a series of tone bursts in six successive 0 db steps.

The input buffer is a unity-gain stable amplifier that can drive the low impedance input of the VCA and an internal rms detector. The value of the averaging capacitor affects sound quality: LTspice downloads and documentation. Do not run input and output traces adjacent to each other. This can be one of 4 stages: In most cases, this limits overload time to less than 35 ms.

Evaluation Boards Pricing displayed is based on 1-piece. For more information about lead-free parts, please consult our Pb Lead free information page. V to 8 V Excellent Load. In addition, MOS inputs. The control circuitry subtracts a dc voltage from this signal, scales it, and sends the result to the VCA to control the gain.

A reference pin allows the user to offset the output voltage.

It provides up to mA. Rmx Page 8 of 2 The breakpoint between the compression region and the limiting region is referred to as the limiting threshold or the rotation point. Increasing the gain increases the common-mode rejection. Design Considerations and Solutions. Designed for use in portable consumer, medical, and. The layout should minimize possible capacitive feedback from adg848 output of the SSM back to its input.

For information on the performance of a specific instrumentation amplifier, see the data sheet for that instrumentation amplifier. This time constant controls both the steady state rkz in the rms detector as well as the release time for compression, that is, the time it takes for the system gain to increase due to a decrease in input signal.
