www.DataSheet4U.com 19-3406; Rev 1; 10/05 200kHz, 4µA, Rail-to-Rail I/O Op Amps with Shutdown General Description The single MAX9910/MAX9911 and dual MAX9912/ MAX9913 operational amplifiers (op amps) feature a maximized ratio of gain bandwidth (GBW) to supply current and are ideal for battery-powered applications such as portable instrumentation, portable medical equipment, and wireless handsets. These CMOS op amps feature an ultra-low input-bias current of 1pA, railto-rail inputs and outputs, low supply current of 4µA, and operate from a single 1.8V to 5.5V supply. For additional power conservation, the MAX9911/MAX9913 feature a low-power shutdown mode that reduces supply current to 1nA, and puts the amplifiers’ outputs in a high-impedance state. These devices are unity-gain stable with a 200kHz GBW product. The MAX9910/MAX9911 are available in 5-pin and 6-pin SC70 packages, respectively. The MAX9912 is available in an 8-pin SOT23 package, and the MAX9913 is available in a 10-pin µMAX® package. All devices are specified over the -40°C to +85°C extended operating temperature range. ♦ 200kHz GBW ♦ Ultra-Low 4µA Supply Current ♦ Single 1.8V to 5.5V Supply Voltage Range ♦ Ultra-Low 1pA Input Bias Current ♦ Rail-to-Rail Input and Output Voltage Ranges ♦ Low ±200µV Input Offset Voltage ♦ Low 0.001µA Shutdown Current ♦ High-Impedance Output During Shutdown (MAX9911/MAX9913) ♦ Unity-Gain Stable ♦ Available in Tiny SC70, SOT23, and µMAX Packages Features MAX9910–MAX9913 Applications Portable Medical Devices Portable Test Equipment Laptops Data-Acquisition Equipment PART MAX9910EXK+T MAX9910EXK-T MAX9911EXT+T MAX9911EXT-T 1.8V TO 5.5V OUTA VDD Ordering Information TEMP RANGE -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C PINPACKAGE 5 SC70-5 5 SC70-5 6 SC70-6 6 SC70-6 8 SOT23-8 8 SOT23-8 10 µMAX 10 µMAX TOP MARK AGA AGA ACA ACA AEJY AEJY — — Typical Operating Circuit MAX9912EKA+T MAX9912EKA-T MAX9913EUB VOUT 25kΩ INA- OUTB MAX9913EUB+ +Denotes lead-free package.
