TI Delivers Integrated Ultrasonic Signal Conditioner

May 30, 2012

Designed for automotive parking distance applications, the PGA450-Q1's single-chip integration brings performance and programmability to TI's catalog portfolio.

DALLAS, TX /PRNewswire/ -- Texas Instruments Inc. (TI) (NASDAQ: TXN) introduced a fully integrated, programmable solution for driving ultrasonic transducers in automotive park distance, blind-spot detection, or similar object detection applications. With its highly configurable burst generator, low-noise amplifier and 12-bit successive-approximation-register (SAR) analog-to-digital converter (ADC), the PGA450-Q1 provides for processing the echo signals and calculating the distance between the transducer and the object. Additionally, the PGA450-Q1 incorporates the physical layer for LIN 2.1 communications, giving flexibility in implementing any needed communication protocol.

Key features and benefits of the PGA450-Q1:

  • Application specific standard product (ASSP): Displaces high-volume, discrete-based systems by offering the same functionality to any customer, economically as an ASSP, reducing design-cycles and non-recurring engineering costs, with no need for intellectual property or market agreements.
  • Fully integrated system-on-chip: Includes all system blocks including regulators, dual NMOS low-side drivers, oscillator and a LIN 2.1 physical interface and protocol for interfacing to provide a cost- and space-optimized solution.
  • Programmable: Possesses highly configurable features, such as burst generator, low-noise amplifier, 12-bit SAR ADC, digital band-pass filter, and digital signal envelope detect, allowing for full configurability to the customer's specific end application.

Tools and Support
The PGA450Q1EVM is available to speed the evaluation of the PGA450-Q1. Priced at $99.00, the evaluation module includes cables, graphical user interface, and example firmware to use with the included sensor.

Availability, Packaging and Pricing
The PGA450-Q1 comes in a TSSOP-28 package and is available now for ordering at a suggested retail price of $2.60 in 1,000-unit quantities.
