  • TL851: Sonar Ranging Control

Product Information

Features

  • Designed for Use With the TL851 in Sonar Ranging Modules Like the SN28827
  • Digitally Controlled Variable-Gain Variable-Bandwidth Amplifier
  • Operational Frequency Range of 20 kHz to 90 kHz
  • TTL-Compatible
  • Operates From Power Sources of 4.5 V to 6.8 V
  • Interfaces to Electrostatic or Piezoelectric Transducers
  • Overall Gain Adjustable With One External Resistor

Description

The TL852 is an economical sonar ranging receiver integrated circuit for use with the TL851 control integrated circuit. A minimum of external components is required for operation, and this amplifier easily interfaces to Polaroid's 50-kHz electrostatic transducer. An external 68-k.

Digital control of amplifier gain is provided with gain control inputs GCA, GCB, GCC, and GCD. These inputs must be driven synchronously (all inputs stable within 0.1 us) to avoid false receive output signals due to invalid logic counts. This can be done easily with the TL851 control integrated circuit. A plot showing relative gain for the various gain steps versus time can be seen in Figure 2. To dampen ringing of the 50-kHz electrostatic transducer, a 5-k resistor from G1IN to XIN is recommended.
