CLC452

Single Supply, Low-Power, High Output,

Current Feedback Amplifier

General Description

The CLC452 has a new output stage that delivers high output drive current (100mA), but consumes minimal quiescent supply current (3.0mA) 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 CLC452 offers superior dynamic performance with a 130MHz small-signal bandwidth, 400V/µs slew rate and 4.5ns rise/fall times (2Vstep). The combination of low quiescent power, high output current drive, and high-speed performance make the CLC452 well suited for many battery-powered personal communication/computing systems.

The ability to drive low-impedance, highly capacitive loads, makes the CLC452 ideal for single ended cable applications. It also drives low impedance loads with minimum distortion. The CLC452 will drive a 100Ω load with only -75/-74dBc second/third

harmonic distortion (Av = +2, Vout = 2Vpp, f = 1MHz). With a 25Ω load, and the same conditions, it produces only -65/-77dBc sec-

ond/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 CLC452 provides excellent -78/-85dBc second/third harmonic

distortion (Av = +2, Vout = 2Vpp, f = 1MHz, RL = 1kΩ) and fast settling time.

Available in SOT23-5, the CLC452 is ideal for applications where space is critical.
