ISUPPLY (Pin 1): Supply Current Programming. The sup-
ply current can be programmed through Pin 1. When
Pin 1 is left open or tied to V+, the supply current defaults
to 800A. Tying a resistor between Pin 1 and Pin 4, the
negative supply pin, will reduce the supply current. The
supply current, as a function of the resistor value, is
shown in Typical Performance Characteristics.
–IN (Pin 2): Inverting Input.
+IN (Pin 3): Noninverting Input.
V– (Pin 4): Negative Supply.
EXT CLOCK IN (Pin 5): Optional External Clock Input. The
LTC1150 has an internal oscillator to control the circuit
operation of the amplifier if Pin 5 is left open or biased at
any DC voltage in the supply voltage range. When an
external clock is desirable, it can be applied to Pin 5. The
applied clock is AC-coupled to the internal circuitry to
simplified interface requirements. The amplitude of the
clock input signal needs to be greater than 2V and the
voltage level has to be within the supply voltage range.
Duty cycle is not critical. The internal chopping frequency
is the external clock frequency divided by four. When
frequency of the external clock falls below 100Hz (internal
chopping at 25Hz), the internal oscillator takes over and
the circuit chops at 550Hz.
OUT (Pin 6): Output.
V+ (Pin 7): Positive Supply.
CLOCK OUT (Pin 8): Clock Output. The signal coming out
of this pin is at the internal oscillator frequency of about
2.2kHz (four times the chopping frequency) and has
voltage levels at VH = VS and VL = VS –4.6. If the circuit is
driven by an external clock, Pin 8 is pulled up to VS.
