16-bit LTC2450 available from Soanar
16-bit LTC2450
16-bit LTC2450 is available from Soanar in a 2mm x 2mm DFN package, making it possible to replace a microcontroller’s embedded ADC with little board space penalty.
The 16-bit LTC2450 is engineered for good DC performance, so designers no longer have to choose between small space, high performance and low cost.
16-bit LTC2450’s linearity, offset error and gain error are all tested and guaranteed over the full industrial temperature range.
The LTC2450’s 4mm² size makes it possible to take an accurate ADC measurement for values such as temperature, current, voltage, or airflow without displacing surrounding circuitry.
This facility is particularly useful in high-density applications such as optical networking cards, data acquisition units and servers. 16-bit LTC2450’s delta sigma core offers 16-bit no missing codes performance.
Integral Non Linearity error (INL) is typically 2 LSBs (maximum of 10 LSBs) and gain error a maximum of 0.02%. Both specifications are guaranteed over the full industrial (-40°C to +85°C) temperature range.
At just 2.8cm x 2.8cm, the DC1067A demo board also includes an LT6660 reference/power supply. Subject to certain eligibility criteria, Linear Technology Corporation and Arrow Northern Europe can provide complimentary LTC2450 demonstration boards to Arrow Innovation readers who enquire via the link below.
