SPICE Analog Simulation Program TINA TI

SPICE Analog Simulation Program TINA TI

TINA is an easy-to-use, but powerful, circuit simulation program based on a SPICE engine. TINA-TI is a fully functional version of TINA, loaded with a library of TI macromodels plus passive and active models.

TINA-TI's new version 7.0 has changes from Version 6.0 in the following areas:

  • TINA-TI provides support for switching power supply devices.
  • TINA-TI has no limit to circuit size.
  • TINA-TI has more SPICE models and example circuits included.
  • User will be notified when an update is available for the tool and TI model library.
  • TINA-TI now supports SMPS simulation capability.
  • Circuits developed in TINA-TI 7.0 will work with TINA Industrial version 7.
  • TINA-TI Version 6.0 is forward compatible with Version 7.0, but not visa versa

Users operating TINA-TI version 6.0 must download the application schematic files separately. Access the Application Schematics here.

TINA's quick start guide, video tutorials, and other documentation.

Application Schematic categories include:

  • Amplifiers - Audio, Comparator, Current Loop, Control Loop, Filters, Oscillators, .. etc.
  • Noise Analysis - Noise Sources
  • Sensor Simulators - RTD Simulator

LM336-2.5 - Voltage Reference Diode

LM336-2.5 - Voltage Reference Diode

The LM136-2.5/LM236-2.5 and LM336-2.5 integrated circuits are precision 2.5V shunt regulator diodes. These monolithic IC voltage references operate as a low-temperature-coefficient 2.5V zener with 0.2 dynamic impedance. A third terminal on the LM136-2.5 allows the reference voltage and temperature coefficient to be trimmed easily.

Features

  • Low temperature coefficient
  • Wide operating current of 400 µA to 10 mA
  • 0.2 dynamic impedance
  • ±1% initial tolerance available
  • Guaranteed temperature stability
  • Easily trimmed for minimum temperature drift
  • Fast turn-on

(This was used by me in the manufacture of Indicators and Controllers and was used in place of ICL8609 (not sure) as that was not in supply)
