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)

Applications:

D Limit Comparators

D Simple Analog to Digital Converters

D Pulse, Squarewave, and Time Delay Generators

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 “ON–OFF” characteristic 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 collector–base 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 common–mode voltage or either input signal voltage should not be allowed to go

negative by more than 0.3V. The upper end of the common–mode 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 = 0Ω with V+ from 5V; and over the full input common–

mode range (0V to V+ – 1.5V).
