LM2917M-8
The LM2907 and LM2917 devices are monolithic
frequency-to-voltage converters with a high gain op
amp designed to operate a relay, lamp, or other load
when the input frequency reaches or exceeds a
selected rate. The tachometer uses a charge pump
technique and offers frequency doubling for lowripple, full-input protection in two versions (8-pin
LM2907 and LM2917), and its output swings to
ground for a zero frequency input.
The op amp is fully compatible with the tachometer
and has a floating transistor as its output. This feature
allows either a ground or supply referred load of up to
50 mA. The collector may be taken above VCC up to a
maximum VCE of 28 V.

LM293H
The LM193-N series consists of two independent
precision voltage comparators with an offset voltage
specification as low as 2.0 mV max for two
comparators which were designed specifically to
operate from a single power supply over a wide range
of voltages. Operation from split power supplies is
also possible and the low power supply current drain
is independent of the magnitude of the power supply
voltage. These comparators also have a unique
characteristic in that the input common-mode voltage
range includes ground, even though operated from a
single power supply voltage.
