The TLV170x family of devices offers a wide supply range, rail-to-rail inputs, low quiescent current, and low propagation delay. All these features come in industry-standard, extremely-small packages, making these devices the best general-purpose comparators available.

The open collector output offers the advantage of allowing the output to be pulled to any voltage rail up to +36 V above the negative power supply, regardless of the TLV170x supply voltage.

These devices are available in single (TLV1701), dual (TLV1702), and quad (TLV1704) channel versions. Low input offset voltage, low input bias currents, low supply current, and open-collector configuration make the TLV170x family flexible enough to handle almost any application, from simple voltage detection to driving a single relay.

All devices are specified for operation across the expanded industrial temperature range of –40°C to +125°C.

CIRCUIT060080 — 具有整合式參考電路的窗型比較器

此電路利用 TLV6710，其中包含兩個比較器和 400 mV 的精密內部參考。監控電壓 (VMON) 由 R1、R2 和 R3 分壓。跨 R2 和 R3 的電壓與 400 mV 內部參考電壓 (VREF) 相比較。如果輸入訊號 (VMON) 在窗口內，則輸出爲高電位。如果訊號位準超出窗口範圍，則輸出為低電位。此範例會採用 TLV6710，其中方便包含兩個比較器和經過 400-mV 閾值修整的通用精密內部參考。另外也可使用兩個分離式比較器和外部參考。
