200kHz, 4A, 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 4A, 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 MAX(R) package. All devices are specified over the -40C to +85C extended operating temperature range. 200kHz GBW Ultra-Low 4A 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 200V Input Offset Voltage Low 0.001A Shutdown Current High-Impedance Output During Shutdown (MAX9911/MAX9913) Unity-Gain Stable Available in Tiny SC70, SOT23, and MAX Packages

MAX9910-MAX9913
Detailed Description
Featuring a maximized ratio of GBW to supply current, low operating supply voltage, low input bias current, and rail-to-rail inputs and outputs, the MAX9910- MAX9913 are an excellent choice for precision or general-purpose, low-current, low-voltage, battery-powered applications. These CMOS devices consume an ultralow 4A (typ) supply current and a 200V (typ) offset voltage. For additional power conservation, the MAX9911/MAX9913 feature a low-power shutdown mode that reduces supply current to 1nA (typ), and puts the amplifiers' output in a high-impedance state. These devices are unity-gain stable with a 200kHz GBW product, driving capacitive loads up to 30pF. The capacitive load can be increased to 250pF when the amplifier is configured for a 10V/V gain.
The MAX9910-MAX9913 are capable of driving the output to within 5mV of both supply rails with a 100k load. These devices can drive a 5k load with swings to within 60mV of the rails. Figure 1 shows the output voltage swing of the MAX9910-MAX9913 configured as a unity-gain buffer powered from a single 3V supply.
Low Input Bias Current
The MAX9910-MAX9913 feature ultra-low 1pA (typ) input bias current. The variation in the input bias current is minimal with changes in the input voltage due to very high input impedance (in the order of 1G).
Applications Information
Driving Capacitive Loads
The MAX9910-MAX9913 amplifiers are unity-gain stable for loads up to 30pF. However, the capacitive load can be increased to 250pF when the amplifier is configured for a minimum gain of 10V/V. Applications that require greater capacitive-drive capability should use an isolation resistor between the output and the capacitive load (Figure 2). Also, in unity-gain applications with relatively small RL (approximately 5k), the capacitive load can be increased up to 200pF.

Rail-to-Rail Inputs and Outputs
All of the MAX9910-MAX9913 amplifiers have a parallelconnected n- and p-channel differential input stage that allows an input common-mode voltage range that extends 100mV beyond the positive and negative supply rails, with excellent common-mode rejection.

Power-Supply Considerations
The MAX9910-MAX9913 are optimized for single 1.8V to 5.5V supply operation. A high amplifier power-supply rejection ratio of 95dB (typ) allows the devices to be powered directly from a battery, simplifying design and extending battery life.

Power-Up Settling Time
The MAX9910-MAX9913 typically require 5s after power-up. Supply settling time depends on the supply voltage, the value of the bypass capacitor, the output impedance of the incoming supply, and any lead resistance or inductance between components. Op-amp settling time depends primarily on the output voltage and is slew-rate limited. Figure 3 shows the MAX991_ in a noninverting voltage follower configuration with the input held at midsupply. The output settles in approximately 18s for VDD = 3V (see the Typical Operating Characteristics for power-up settling time).
Figure 1. Rail-to-Rail Output Voltage Range
Shutdown Mode
The MAX9911/MAX9913 feature active-low shutdown inputs. The MAX9911/MAX9913 enter shutdown in 2s (typ) and exit in 30s (typ). The amplifiers' outputs are in a high-impedance state in shutdown mode. Drive SHDN low to enter shutdown. Drive SHDN high to enable the amplifier. The MAX9913 dual-amplifier features separate shutdown inputs. Shut down both amplifiers for the lowest quiescent current.

Power-Supply Bypassing and Layout
To minimize noise, bypass VDD with a 0.1F capacitor to ground, as close to the pin as possible. Good layout techniques optimize performance by decreasing the amount of stray capacitance and inductance to the op amps' inputs and outputs. Minimize stray capacitance and inductance by placing external components close to the IC.
