Description The CLC450 has a new output stage that delivers high output drive current (100mA), but consumes minimal quiescent supply current (1.5mA) from a single 5V supply. Its current feedback architecture, fabricated in an advanced complementary 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 -3dB 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 combination of low quiescent power, high output current drive, and high speed performance make the CLC450 well suited for many battery powered personal communication/computing 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 100
load with only -75/-64dBc second/third harmonic distortion (AV =+2, VOUT = 2VPP, f = 1MHz). With a 25 load, and the same conditions, it produces only -70/-60dBc 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/-75dBc second/third harmonic distortion (AV= +2, VOUT = 2VPP, f = 1MHz, RL = 1k) and fast settling time.
Available in SOT23-5, the CLC450 is ideal for applications where space is critical.
