MAX9502

19-3674; Rev 0; 5/05 2.5V Video Amplifier with Reconstruction Filter www.datasheet4u.com General Description Features ♦ Tiny 6-Pin µDFN (1mm x 1.5mm x 0.8mm) and 5-Pin SC70 Packages ♦ DC-Coupled Input and Output Save Board Space ♦ 4-Pole Chebyshev Filter ♦ 5.5MHz Passband ♦ 55dB Attenuation at 27MHz ♦ 0.01µA Low-Current Shutdown Mode ♦ 2.5V to 3.6V Single-Supply Operation ♦ Video Amplifier with Fixed Gains of +6dB (MAX9502G) or +12dB (MAX9502M) MAX9502 The MAX9502 small, low-power video amplifier with integrated reconstruction filter operates from a supply voltage as low as 2.5V. The small size and the low minimum supply voltage make the MAX9502 ideal for portable applications such as mobile phones, digital still cameras, and camcorders. The MAX9502 DC-couples the input and the output, resulting in a very small solution. The MAX9502 input can be directly connected to the output of a video digital-toanalog converter (DAC). The reconstruction filter is implemented as a 4th-order Chebyshev with a minimum passband of 5.5MHz, 3dB attenuation at 8MHz, and 55dB attenuation at 27MHz. The output amplifier provides a closed-loop gain of +6dB (MAX9502G) or +12dB (MAX9502M), and can drive a 2VP-P video signal into a 150Ω load to ground. The output signal is level-shifted so the sync tip is 110mV (typ) above ground. The MAX9502 operates from a 2.5V to 3.6V single supply and consumes only 5.3mA quiescent supply current. An active-low shutdown mode reduces the supply current to 0.01µA....
