TLV3491 单路毫微瓦功耗推挽输出比较器
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 space-restricted 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
