Overview
The TLV3201AIDCKR, produced by Texas Instruments, is a single-channel comparator that offers a unique blend of high speed and low power consumption. This device is part of the TLV320x family, which includes both single-channel (TLV3201) and dual-channel (TLV3202) versions. The TLV3201 is designed to operate with a propagation delay of just 40ns, making it highly suitable for applications requiring fast response times.
The device is available in compact packages such as the 5-pin SOT-23 and 5-pin SC70, making it ideal for space-constrained designs. It operates over a wide supply voltage range of 2.7V to 5.5V and is specified for use across an industrial temperature range of –40°C to 125°C.
