R1540S001B
R1540S001B is High Noise Immunity 42V Input Voltage 70mA Voltage Tracker manufactured by RICOH.
- Part of the R1540N001B comparator family.
- Part of the R1540N001B comparator family.
OVERVIEW
The R1540x is a voltage tracker featuring input voltage in the range of 3.5 V to 42 V. Highly accurate output voltage which attributes to CE/ADJ pin achieves successful sequence control of the integrated off-board sensor module. Strong enough not to require the circuit to avoid external electromagnetic interference (EMI) and this contributes space saving.
KEY BENEFITS
- Excellent noise immunity provides effective shielding against EMI.
- Lower stand-by current consumption leads to energy saving of the whole system to prolong battery life.
- Response to requirements for sequence control in the system with integrated sensors.
