general description the max4452/max4352 single, max4453/max4353dual, and max4454/max4354 quad amplifiers combine high-speed performance with ultra-low power con- sumption. the max4452/max4453/max4454 are unity- gain stable and achieve a -3db bandwidth of 200mhz, while the max4352/max4353/max4354 are compen- sated for a minimum closed-loop gain of +5v/v and achieve a 80mhz -3db bandwidth. these devices con- sume only 620? of supply current per amplifier. these amplifiers operate from a +2.7v to +5.25v single supply and feature rail-to-rail outputs. along with an excellent speed/power ratio of 323mhz/ma, these devices feature a slew rate of 95v/? and fast 20ns rise and fall times. these devices are ideal for low- power/low-voltage systems that require wide bandwidth such as cell phones and keyless entry systems. the max4452/max4352 are available in miniature 5-pin sc70 and sot23 packages, while the max4453/ max4353 are available in tiny 8-pin sot23, thin sot23, and so packages. the max4454/max4354 are avail- able in space-saving 14-pin tssop and so packages. ________________________applications battery-powered instrumentscellular telephones portable communications keyless entry baseband applications features ? ultra-low 620a supply current ? high speed (max4452/max4453/max4454) 200mhz -3db bandwidth30mhz 0.1db gain flatness 95v/s slew rate ? high speed (max4352/max4353/max4354) 80mhz -3db bandwidth4mhz 0.1db gain flatness 240v/s slew rate ? single +3v/+5v operation ? rail-to-rail outputs ? ultra-small sc70-5, sot23-5, sot23-8 and thinsot23-8 packages max4452/max4453/max4454/max4352/max4353/max4354 low-cost, +3v/+5v, 620a, 200mhz, single-supply op amps with rail-to-rail outputs ________________________________________________________________ maxim integrated products 1 19-1824; rev 1; 1/05 ordering information pa r t t em p ra n g e pin - pa c k a g e to p m a r k m a x4 4 5 2 e x k- t - 40 c to + 85 c 5 s c 70- 5a b i m ax 4452e u k- t - 40 c to + 85 c 5 s ot23- 5 ad o v m a x4 4 5 3 e ka- t - 40 c to + 85 c 8 s ot23- 8 aad s m ax 4453e z a- t - 40 c to + 85 c 8 thi n s o t23- 8 aaab m ax 4453e s a - 40 c to + 85 c 8 s o m a x4 4 5 4 e u d - 40 c to + 85 c 14 ts s o p m ax 4454e s d - 40 c to + 85 c 14 s o m a x4 3 5 2 e x k- t - 40 c to + 85 c 5 s c 70- 5 abj m ax 4352e u k- t - 40 c to + 85 c 5 s ot23- 5 ad ow m a x4 3 5 3 e ka- t - 40 c to + 85 c 8 s ot23- 8 aad t m ax 4353e s a - 40 c to + 85 c 8 s o m a x4 3 5 4 e u d - 40 c to + 85 c 14 ts s o p m ax 4354e s d - 40 c to + 85 c 14 s o part no. of amps min gain gain bandwidth (mhz) slew rate (v/ s) max4452 1 1 200 95 max4352 1 5 400 240 max4453 2 1 200 95 max4353 2 5 400 240 max4454 4 1 200 95 max4354 4 5 400 240 selector guide for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. typical operating characteristic pin configurations appear at end of data sheet. max4452/3/4 toc01 0.40 0.45 0.550.50 0.70 0.750.65 0.60 0.80 supply current (ma) 2.7 3.5 3.9 3.1 4.3 4.7 5.1 5.5 supply voltage (v) supply current vs. supply voltage (per amplifier) downloaded from: http:///
