3 Description
The TLV3541, TLV3542 and TLV3544 are single-, dual-, and quad-channel, low-power (5.2-mA per channel), high-speed, unity-gain stable, rail-to-rail input/output operational amplifiers (op amps) designed for video and other applications that require wide bandwidth.
Consuming only 6.5 mA (maximum) of supply current, these devices feature 200-MHz gain-bandwidth product, 150-V/μs slew rate, and a low 7.5 nV/√Hz of input noise at f = 1 MHz. The combination of high bandwidth, high slew rate, and low noise make the TLV354x family suitable for low voltage, high-speed signal conditioning systems.
The TLV354x series of op amps are optimized for operation on single or dual supplies as low as 2.5 V (±1.25 V) and up to 5.5 V (±2.75 V). Common-mode input range extends beyond the supplies. The output swing is within 100 mV of the rails, and supports a wide dynamic range.
The TLV354x devices are specified from –40°C to +125°C. The TLV354x family can be used as a plug-in replacement for many commercially available wide bandwidth op amps.
