The LM211D by STMicroelectronics is an 8-pin Small Outline Package (SMT) with a universal voltage range of 5÷30V. It is a comparator with one comparator inside. The LM211D is designed to provide accurate and reliable interface between low-level analog signals and discrete digital circuitry. It is suitable for use in power-sensitive applications where space constraints limit component selection.The LM211D is designed to have one comparator that offers fast response for light loads, low power shutdown for battery applications, low input offset voltage, low input offset voltage drift, low input bias current, and low output saturation voltage. It also features excellent input common-mode voltage range, wide gain bandwidth with up to 12MHz single-ended bandwidth, high output current, and an extended temperature range of -25°C to +150°C. It is ideal for applications such as signal conditioning, comparator circuit conversions, temperature monitoring, and audio amplifier oversampling and limiting.
