CLC450
CLC450 is Single Supply/ Low-Power/ High Output/ Current Feedback Amplifier manufactured by National Semiconductor.
Description
The CLC450 has a new output stage that delivers high output drive current (100m A), but consumes minimal quiescent supply current (1.5m A) from a single 5V supply. Its current feedback architecture, fabricated in an advanced plementary bipolar process, maintains consistent performance over a wide range of gains and signal levels, and has a linear-phase response up to one half of the -3d B frequency. The CLC450 offers superior dynamic performance with a 100MHz small-signal bandwidth, 280V/µs slew rate and 6.1ns rise/fall times (2Vstep). The bination of low quiescent power, high output current drive, and high-speed performance make the CLC450 well suited for many battery-powered personal munication/puting systems. The ability to drive low-impedance, highly capacitive loads, makes the CLC450 ideal for single ended cable applications. It also drives low impedance loads with minimum distortion. The CLC450 will drive a 100Ω load with only -75/-64d Bc second/third harmonic distortion (Av = +2, Vout = 2Vpp, f = 1MHz). With a 25Ω load, and the same conditions, it produces only -70/-60d Bc second/third harmonic distortion. It is also optimized for driving high currents into single-ended transformers and coils. When driving the input of high-resolution A/D converters, the CLC450 provides excellent -79/-75d Bc second/third harmonic distortion (Av = +2, Vout = 2Vpp, f = 1MHz, RL = 1kΩ) and fast settling time. Available in SOT23-5, the CLC450 is ideal for applications where space is critical.
