The S-19760/1 Series is primarily used as a reference voltage for A/D converters, which convert analog sensor signals into digital values.
The key features of the S-19760/1 Series include achieving the industry’s highest(*1) output voltage accuracy of ±0.1% and the industry’s lowest output voltage temperature coefficient of ±20ppm/°C.
This enables the output of a highly precise reference voltage even in severe temperature environments, contributing to improved sensor readout accuracy. Furthermore, with its integrated filter circuit, the product series features an ultra-low output noise of just 28µVrms.
This minimizes measurement errors in A/D converters during the conversion of sensor signals into digital values.
The S-19761 Series also features a maximum shunt current of 30mA, allowing a single shunt reference IC to be used as the reference voltage for multiple circuits, thereby reducing the number of components, saving space, and contributing to cost reduction.
In addition to the standard SOT-23-3 (2.8 x 2.9 x t1.3 mm) package, the lineup also includes the ultra-small/thin HSNT-8(1616)B (1.6 x 1.6 x t0.41 mm) package, enabling space-saving mounting.
Vehicles are equipped with various sensors that precisely monitor the constantly changing vehicle conditions.
For example, in EV/HEV inverters, sensors monitor current, voltage, and motor angle to enable precise motor control.
When these sensor signals are processed by an A/D converter, a highly precise reference voltage is essential to ensure precise digital conversion.
By using the S-19760/1 Series, featuring industry-leading output voltage accuracy and temperature coefficient, as a reference voltage, users can ensure high-precision inverter monitoring and control even in harsh environments, thereby supporting enhanced vehicle safety.
Moreover, as the number of sensors installed in vehicles continues to increase, this product contributes to component miniaturization and reduced component count.
