Semiconductor Components NCS21801, NCS21802, NCS21803, NCS21804 Datasheet
Precision Operational
Amplifier, 10 mV, Zero-Drift,
1.6 V to 5.5 V Supply,
1.5 MHz
NCS21801, NCS21802,
NCS21803, NCS21804
The NCS21801, NCS21802, NCS21803, and NCS21804 are
precision op amps featuring low input offset voltage and low offset
drift over time and temperature. The common mode voltage range
extends 100 mV beyond the supply rails, which makes it suitable for
both high−side and low−side current sensing applications.
The NCS2180x is available in single, dual, and quad channel
configurations. All versions are specified for operation from −40°C to
+125°C. NCV prefix parts are automotive grade 1 qualified and offer
performance over the extended temperature range from −40°C to
+150°C.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Refer to ELECTRICAL CHARACTERISTICS, RECOMMENDED OPERATING RANGES and/or APPLICATION INFORMATION for safe
operating parameters
2. Terminals are diode−clamped to the power−supply rails. Input signals that can swing more than 0.3 V beyond the supply rails should be
current limited to ±10 mA or less. Output terminals should not be driven by external sources.
3. Short circuits to either rail can cause an increase in the junction temperature. The total power dissipation must be limited to prevent the
junction temperature from exceeding the 150°C limit.
4. This device series incorporates ESD protection and is tested by the following methods:
ESD Human Body Model tested per JEDEC standard JS−001−2017 (AEC−Q100−002)
ESD Charged Device Model tested per JEDEC standard JS−002−2014 (AEC−Q100−011)
