MC1403P1 DIP-8 Low Voltage Reference IC Chip
The MC1403 is a precision band-gap low voltage reference IC. It is engineered for high-accuracy applications, including critical instrumentation and D/A (Digital-to-Analog) converters. This chip is designed to provide a stable reference for D/A converters with up to 12 bits of accuracy and can also be used as a reference in power supply applications.
✨Features
- Stable 2.5 V Output: Provides a precise 2.5 V output with a tight tolerance of ±25 mV.
- Wide Input Voltage Range: Operates over a broad input voltage from 4.5 V to 40 V.
- Low Quiescent Current: Consumes a typically low 1.2 mA of quiescent current.
- High Output Current: Capable of sourcing up to 10 mA of output current.
- Excellent Thermal Stability: Features a very low typical temperature coefficient of 10 ppm/°C.
