TLV904x Micropower Operational Amplifiers Texas Instruments TLV904x Micropower Operational Amplifiers include single (TLV9041), dual (TLV9042), and quad-channel (TLV9044) ultra low-voltage (1.2V to 5.5V) operational amplifiers (op amps). These op amps come with rail-to-rail input and output swing capabilities. These op amps provide a cost-effective solution for power and space-constrained applications such as battery-powered IoT devices, wearable electronics, and personal electronics, where a low-voltage operation is usually desired. TLV904x is one of the few op amp families in the industry that enables 1.5V coin cell battery-powered applications.
