Supply Current Programming. The sup- simplified interface requirements. The amplitude of the ply current can be programmed through Pin 1. When clock input signal needs to be greater than 2V and the Pin 1 is left open or tied to V+, the supply current defaults voltage level has to be within the supply voltage range. to 800µA. Tying a resistor between Pin 1 and Pin 4, the Duty cycle is not critical. The internal chopping frequency negative supply pin, will reduce the supply current. The is the external clock frequency divided by four. When supply current, as a function of the resistor value, is frequency of the external clock falls below 100Hz (internal shown in Typical Performance Characteristics. chopping at 25Hz), the internal oscillator takes over and the circuit chops at 550Hz.
