The TLV245x is a family of rail-to-rail input/output operational amplifiers that sets a new performance point for supply current and ac performance. These devices consume a mere 23 µA/channel while offering 220 kHz of gain-bandwidth product, much higher than competitive devices with similar supply current levels. Along with increased ac performance, the amplifier provides high output drive capability, solving a major shortcoming of older micropower rail-to-rail input/output operational amplifiers. The TLV245x can swing to within 250 mV of each supply rail while driving a 2.5-mA load. Both the inputs and outputs swing rail-to-rail for increased dynamic range in low-voltage applications. This performance makes the TLV245x family ideal for portable medical equipment, patient monitoring systems, and data acquisition.
The TLV2450 series comprises ultra‑low‑power rail‑to‑rail input/output operational amplifiers with shutdown capability. Each device consumes only 23 µA per channel while delivering a 220 kHz gain‑bandwidth product and up to +10 mA output drive, making them suitable for portable medical and data‑acquisition applications.
The family is offered in several package types (SOT‑23, MSOP, TSSOP) and supports operation from 2.7 V to 6 V. A dedicated shutdown pin reduces quiescent current to 16 nA per channel. Detailed electrical characteristics, absolute‑maximum ratings, and recommended operating conditions are provided for temperatures ranging from –40 °C to 125 °C.
