Intersil DG445DJ

SPST - NC1:1485 Ом5 В ~ 34 В

Overview

Maxim's redesigned DG444/DG445DJ analog switches now feature on-resistance matching (4 max) between switches and guaranteed on-resistance flatness over the signal range (9 max). These low on-resistance switches conduct equally well in either direction. They guarantee low charge injection (10pC max), low power consumption (35μW max), and an ESD tolerance of 2000V minimum per Method 3015.7. The new design offers lower off-leakage current over temperature (less than 5nA at +85°C). The DG444/DG445DJ are quad, single-pole/single-throw (SPST) analog switches. The DG444 has four normally closed switches and the DG445DJ has four normally open switches. Switching times are less than 250ns for tON and less than 70ns for tOFF. Operation is from a single +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. Maxim's improved DG444/DG445DJ continue to be fabricated with a 44V silicon-gate process.
