Texas Instruments has developed the industry's first solution that integrates mobile WLAN (mWLAN), Bluetooth and FM stereo audio all in a space-saving platform for mobile phones.
Although designed for next-generation industrial process control, the REF50xx is also a good fit for a wide range of applications including medical instrumentation, precision data acquisition and test and measurement.
The REF50xx has high output current of +/-10mA that provides accurate voltage reference to the ADC without an additional op amp buffer.
High accuracy (0.05% maximum) and low output voltage noise (7.5uV peak-peak for 2.5V output) enable peak performance of the ADC in high-resolution applications.
The low temperature drift minimises system error over temperature.
With a wide supply range from the output voltage plus 200mV to 18V, the REF50xx delivers top system performance.
The REF50xx family offers six output voltages: 2.048V (REF5020), 2.5V (REF5025), 3.0V (REF5030), 4.096V (REF5040), 4.5V (REF5045) and 5V (REF5050).
The devices feature standardised pinouts that include a trim pin for +/-15mV output voltage adjust and a temp pin for temperature monitoring.
All models in this family are specified for the wide industrial temperature range of -40 to +125C.
The REF50xx family of voltage references is available now in both standard- and high-grade versions in SO-8 packages from TI and its authorised distributors.
MSOP-8 packages will be offered in Q3 2007.
The standard grade devices are priced from US $1.85 and the high-grade devices are priced from $3.50 in 1000 piece quantities (suggested resale pricing).
