Low Power Low Offset Voltage Comparator
Description:
The NTE834 and NTE834SM are precision voltage comparators designed 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 has a unique characteristic in that the input common–mode voltage range
includes GND, even though operated from a single power supply voltage.
Features:
D Wide Single Supply Voltage Range: 2V to 36V
D Very Low Supply Current Drain: 0.8mA Typ
D Low Input Biasing Current: 25nA
D Low Offset Voltage: ±3mV
D Low Input Offset Current: ±5nA
D Output Voltage Compatible with TTL, DTL, ECL, MOS, and CMOS Logic Systems
D Available in Standard 14–Lead DIP (NTE834) and Surface Mount SOIC–14 (NTE834SM)

Note 1 For operating at high temperatures, these devices must be derated based on a +125°C maxi-
mum junction temperature and a thermal resistance of +175°C/W which applies for the device
soldered to a printed circuit board, operating in ambient still air. The low bias dissipation and
the ONOFFcharacteristic of the outputs keeps the chip dissipation very low (PD 100mW),
provided the output transistors are allowed to saturate.
Note 2 Short circuits from the output to V+ can cause excessive heating and eventual destruction.
The maximum output current is approximately 20mA independent of the magnitude of V+.
Note 3 This input current will only exist when the voltage at any of the input leads is driven negative.
It is due to the collectorbase junction of the input PNP transistors becoming forward biased
and thereby acting as input diode clamps.
Note 4 The direction of the input current is out of the IC due to the PNP input stage. This current
is essentially constant, independent of the state of the output so no loading change exists
on the reference to input lines.
Note 5 The input commonmode voltage or either input signal voltage should not be allowed to go
negative by more than 0.3V. The upper end of the commonmode voltage range is V+ 1.5V,
but either or both inputs can go to +30V without damage.
Note 6. At output switch point, VO 1.4V, RS = 0with V+ from 5V; and over the full input common
mode range (0V to V+ 1.5V).
