MAX4198/MAX4199 19-1445 Rev 1 6/04 Micropower, Single-Supply, Rail-to-Rail Precision Differential Amplifiers General Description Features The MAX4198/MAX4199 low-power, rail-to-rail differential Low 0.01% Gain Error amplifiers are ideal for single-supply applications that High Common-Mode Rejection: 110dB (MAX4199) benefit from a low 0.01% gain error. The MAX4198 is fac- tory trimmed to a fixed gain of +1V/V, and the MAX4199 10V Input Offset Voltage (MAX4199) is trimmed to a fixed gain of +10V/V. Capable of operat- 30V Input Offset Voltage (MAX4198) ing from a single +2.7V to +7.5V supply or from dual +2.7V to +7.5V Single-Supply Operation 1.35V to 3.75V supplies, they consume only 42A while achieving -3dB bandwidths of 175kHz (MAX4198) 42A Supply Current and 45kHz (MAX4199). These amplifiers feature a shut- 175kHz (MAX4198) and 45kHz (MAX4199) down mode that reduces the supply current to 6.5A. -3dB Bandwidth The MAX4198/MAX4199 can drive 5k loads to within 100mV from each rail. The standard differential amplifi- 6.5A Shutdown Current er configurations provide common-mode rejection of Rail-to-Rail Outputs Drive 5k Loads 90dB for the MAX4198 and 110dB for the MAX4199. The input common-mode voltage range for the Input Voltage Range Extends 100mV Beyond-the- MAX4198 extends 100mV Beyond-the-Rails. Rails (MAX4198) The MAX4198/MAX4199 are offered in a space-saving Available in Space-Saving 8-Pin MAX Package 8-pin MAX package.
