www.DataSheet4U.com 19-3407; Rev 1; 10/05 1MHz, 20µA, Rail-to-Rail I/O Op Amps with Shutdown General Description The single MAX9914/MAX9915 and dual MAX9916/ MAX9917 operational amplifiers feature maximized ratio of gain bandwidth 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 1pA input bias current, rail-to-rail inputs and outputs, low 20µA supply current, and operate from a single 1.8V to 5.5V supply. For additional power conservation, the MAX9915/MAX9917 feature a low-power shutdown mode that reduces supply current to 1nA, and puts the amplifier outputs in a high-impedance state. These devices are unity-gain stable with a 1MHz gain-bandwidth product. The MAX9914 and MAX9915 are available in 5-pin and 6-pin SC70 packages, respectively. The MAX9916 is available in an 8-pin SOT23 package, and the MAX9917 in a 10-pin µMAX® package. All devices are specified over the -40°C to +85°C extended operating temperature range. ♦ High 1MHz GBW ♦ Ultra-Low 20µA 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 (MAX9915/MAX9917) ♦ Unity-Gain Stable ♦ Available in Tiny SC70, SOT23, and µMAX Packages Features MAX9914–MAX9917 Applications Portable Medical Devices Portable Test Equipment RF Tags Laptops Data-Acquisition Equipment PART MAX9914EXK+T MAX9914EXK-T MAX9915EXT+T MAX9915EXT-T MAX9916EKA+T MAX9916EKA-T MAX9917EUB MAX9917EUB+ MAX9916 IN+ INA+ OUTA OUT R1 47kΩ INAGAIN = RG* ININB+ OUTB R3 10kΩ INBVSS R2 10kΩ (R1 + R2 + R3 + R4) (R2 + R3) 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 AGB AGB ACB ACB AEJZ AEJZ — — Typical Operating Circuit 3V VDD +Denotes lead-free package.
