1.8V, Nanopower, PUSH-PULL OUTPUT COMPARATOR
FEATURES
q VERY LOW SUPPLY CURRENT: 0.8µA (typ) q INPUT COMMON-MODE RANGE 200mV BEYOND SUPPLY RAILS q SUPPLY VOLTAGE: +1.8V to +5.5V q HIGH SPEED: 6µs q PUSH-PULL CMOS OUTPUT STAGE q SMALL PACKAGES: SOT23-5 (Single) SOT23-8 (Dual)
DESCRIPTION
The TLV349x family of push-pull output comparators features a fast 6µs response time and < 1.2µA (max) nanopower capability, allowing operation from 1.8V – 5.5V. Input common-mode range beyond supply rails make the TLV349x an ideal choice for low-voltage applications. Micro-sized packages provide options for portable and spacerestricted applications. The single (TLV3491) is available in SOT23-5 and SO-8. The dual (TLV3492) comes in SOT23-8 and SO-8. The quad (TLV3494) is available in TSSOP-14 and SO-14. The TLV349x is excellent for power-sensitive, low-voltage (2-cell) applications.
