single/dual sc70, zero-drift, high-efficiency, 1.5mhz op amps with rrio max9617Cmax9620 _______________________________________________________________________________________ 7 detailed description the max9617Cmax9620 are precision, low-power op amps ideal for signal processing applications. the max9617, max9619, and max9620 are single-channel devices. the max9618 is a dual-channel device. these devices use an innovative autozero technique that allows precision and low noise with a minimum amount of power. the low input offset voltage, cmos inputs, and the absence of 1/f noise allows for optimization of active filter designs. the max9617Cmax9620 achieve rail-to-rail performance at the input through the use of a low-noise charge pump. this ensures a glitch-free, common-mode input voltage range extending from the negative supply rail up to the positive supply rail, eliminating crossover distortion common to traditional n-channel/p-channel cmos pair inputs, reducing harmonic distortion at the output. the max9619 features a shutdown mode that greatly reduc - es quiescent current when the device is not operational. autozero the max9617Cmax9620 feature an autozero circuit that allows the device to achieve less than 10 f v (max) of input offset voltage and eliminates the 1/f noise. internal charge pump an internal charge pump provides an internal supply typi - cally 1v beyond the upper rail. this internal rail allows the max9617Cmax9620 to achieve true rail-to-rail inputs and outputs, while providing excellent common-mode rejec - tion, power-supply rejection ratios, and gain linearity. the charge pump requires no external components, and in most applications is entirely transparent to the user. the operating frequency is well beyond the unity-gain frequency of the amplifier, avoiding aliasing or other sig - nal integrity issues in sensitive applications. shutdown operation the max9619 features an active-low shutdown mode that lowers the quiescent current to less than 300na. in shutdown mode, the inputs and output are high imped - ance. this allows multiple devices to be multiplexed onto a single line without the use of external buffers. pull shdn high for normal operation. the shutdown high (v ih ) and low (v il ) threshold voltages are designed for ease of integration with digital con - trols like microcontroller outputs. these thresholds are independent of supply, eliminating the need for external pulldown circuitry. applications information the max9617Cmax9620 low-power, low-noise, and precision operational amplifiers are designed for appli - cations in the portable medical, such as ecg and pulse oximetry, portable consumer, and industrial markets. the max9617Cmax9620 are also ideal for loop-powered systems that interface with pressure sensors or strain gauges. capacitive-load stability driving large capacitive loads can cause instability in many op amps. the max9617Cmax9620 are stable with capacitive loads up to 400pf. stability with higher capacitive loads can be improved by adding an isolation resistor in series with the op-amp output. this resistor improves the circuits phase margin by isolating the load capacitor from the amplifiers output. the graph in the typical operating characteristics gives the stable oper - ation region for capacitive load versus isolation resistors. figure 1. typical application circuit: sallen-key active lowpass filter max9617 adc +5v v in
single/dual sc70, zero-drift, high-efficiency, 1.5mhz op amps with rrio max9617Cmax9620 8 ______________________________________________________________________________________ power supplies and layout the max9617Cmax9620 operate either with a single supply from +1.6v to +5.5v with respect to ground or with dual supplies from q 0.8v to q 2.75v. when used with dual supplies, bypass both supplies with their own 0.1 f f capacitor to ground. when used with a single supply, bypass v dd with a 0.1 f f capacitor to ground. careful layout technique helps optimize performance by decreasing the amount of stray capacitance at the op amps inputs and outputs. to decrease stray capaci - tance, minimize trace lengths by placing external com - ponents close to the op amps pins. chip information process: bicmos
