The CD8541/CD8542/CD8544 are single, dual, and quad rail to-rail input and output, single-supply amplifiers featuring very low supply current and 1.1 MHz bandwidth. All are guaranteed to operate from a 2.7 V single supply as well as a 5 V supply. These parts provide 1.1MHz bandwidth at a low current consumption of 45 μA per amplifier. Low input bias currents enable the CD8541/CD8542/CD8544 to be used for integrators, photodiode amplifiers, piezoelectric sensors, and other applications with high source impedance. The supply current is only 45 μA per amplifier, ideal for battery operation. Rail-to-rail inputs and outputs are useful to designers buffering ASICs in single-supply systems.
The CD8541/CD8542/CD8544 are optimized to maintain high gains at lower supply voltages, making them useful for active filters and gain stages. The CD8541/CD8542/CD8544 are specified over the extended industrial temperature range (–40°C to +125°C). The CD8541 is available in 5-lead SOT-23, 5-lead SC70, and 8-lead SOIC packages. The CD8542 is available in 8-lead SOIC, 8-lead MSOP, and 8-lead TSSOP surface-mount packages. The CD8544 is available in 14-lead narrow SOIC and 14-lead TSSOP surface-mount packages. All MSOP, SC70, and SOT versions are available in tape and reel only. See the Ordering Guide for automotive models.
