LM2907-N 的說明

The LM2907 and LM2917 devices are monolithic frequency-to-voltage converters with a high gain op amp designed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate. The tachometer uses a charge pump technique and offers frequency doubling for low-ripple, full-input protection in two versions (8-pin LM2907 and LM2917), and its output swings to ground for a zero frequency input.

The op amp is fully compatible with the tachometer and has a floating transistor as its output. This feature allows either a ground or supply referred load of up to 50 mA. The collector may be taken above VCC up to a maximum VCE of 28 V.

The two basic configurations offered include an 8-pin device with a input and an internal connection between the tachometer output and the op amp noninverting input. This version is well suited for single speed or frequency switching or fully buffered frequency-to-voltage conversion applications.

The more versatile configurations provide differential tachometer input and uncommitted op amp inputs. With this version the tachometer input may be floated and the op amp becomes suitable for active filter conditioning of the tachometer output.

Both of these configurations are available with an active shunt regulator connected across the power leads. The regulator clamps the supply such that stable frequency-to-voltage and frequency-to-current operations are possible with any supply voltage and a suitable resistor.

包裝類型選項

您可依零件數量選擇不同包裝類型選項,包含完整捲盤、客製化捲盤、剪切捲帶、承載管或盤。

客製化捲盤是從一個捲盤上剪切下來的連續剪切捲帶,以維持批次和日期代碼可追溯性,依要求剪切至確切數量。依照業界標準,銅墊片會在剪切捲帶兩側連接 18 英吋前後導帶,以直接送至自動組裝機器。針對客製化捲盤訂單,TI 將酌收捲帶封裝費用。

剪切捲帶是從捲盤剪切下來的一段捲帶。TI 可能使用多條剪切捲帶或承載盒,以滿足訂單要求數量。

TI 常以盒裝或管裝、盤裝方式運送承載管裝置,視現有庫存而定。所有捲帶、管或樣本盒之封裝,皆符合公司內部靜電放電與防潮保護包裝要求。
