TLV2341数据手册TI中文资料规格书

描述 Description

The TLV2341 operational amplifier has been specifically developed for low-voltage, single-supply applications and is fully specified to operate over a voltage range of 2 V to 8 V. The device uses the Texas Instruments silicon-gate LinCMOSTM technology to facilitate low-power, low-voltage operation and excellent offset-voltage stability. LinCMOSTM technology also enables extremely high input impedance and low bias currents allowing direct interface to high-impedance sources. The TLV2341 offers a bias-select feature, which allows the device to be programmed with a wide range of different supply currents and therefore different levels of ac performance. The supply current can be set at 17 uA, 250 uA, or 1.5 mA, which results in slew-rate specifications between 0.02 and 2.1 V/us (at 3 V). The TLV2341 operational amplifiers are especially well suited to single-supply applications and are fully specified and characterized at 3-V and 5-V power supplies. This low-voltage single-supply operation combined with low power consumption makes this device a good choice for remote, inaccessible, or portable battery-powered applications. The common-mode input range includes the negative rail. The device inputs and outputs are designed to withstand -100-mA currents without sustaining latch-up. The TLV2341 incorporates internal ESD-protection circuits that prevents functional failures at voltages up to 2000 V as tested under MIL-STD 883 C, Methods 3015.2; however, care should be exercised in handling these devices as exposure to ESD may result in the degradation of the device parametric performance. The D package is available taped and reeled. Add R suffix to the device type (e.g., TLV2341IDR). The PW package is only available left-end taped and reeled (e.g., TLV2341IPWLE).
