ZRA400Y02

PRECISION 4.0 VOLT MICROPOWER VOLTAGE REFERENCE ISSUE 1 - JANUARY 1996 ZRA400 No stabilising capacitor required Typical TC 15ppm/°C Typical slope resistance 0.55Ω ± 3%, 2% and 1% tolerance Industrial temperature range Operating current 50µA to 5mA Battery powered and portable equipment. Metering and measurement systems. Instrumentation. Test equipment. Data acquisition systems. Precision power supplies. Crystal oscillators DEVICE DESCRIPTION The ZRA400 uses a bandgap circuit design to achieve a precision micropower voltage reference of 4.096 volts. The device is available in small outline surface mount packages, ideal for applications where space saving is important. The ZRA400 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZRA400 is recommended for operation between 50µA and 5mA and so is ideally suited to low power and battery powered applications. Excellent performance is maintained to a suggested absolute maximum of 25mA, however the rugged design and 20 volt processing allows the reference to withstand transient effects and currents up to 200mA. Superior switching capability allows the device to reach stable operating conditions in only a few microseconds. APPLICATIONS FEATURES Small outline SO8, SOT23 and TO92 style packages.
