LMV301 www.ti.com SNOS968A – MAY 2004 – REVISED MAY 2013 LMV301 Low Input Bias Current, 1.8V Op Amp w/ Rail-to-Rail Output Check for Samples: LMV301 FEATURES 1 2 Input Bias Current: 0.182 pA Gain Bandwidth Product: 1 MHz Supply Voltage at 1.8V: 1.8 to 5 V Supply Current: 150 µA Input Referred Voltage Noise at 1kHz: 40nV/√Hz DC Gain (600Ω Load): 100 dB Output Voltage Range at 1.8V: 0.024 to 1.77 V Input Common-Mode Voltage Range: −0.3 to ±1.2 V APPLICATIONS Thermocouple Amplifiers Photo Current Amplifiers Transducer Amplifiers Sample and Hold Circuits Low Frequency Active Filters DESCRIPTION The LMV301 CMOS operational amplifier is ideal for single supply, low voltage operation with an ensured operating voltage range from 1.8V to 5V. The low input bias current of less than 0.182pA typical, eliminates input voltage errors that may originate from small input signals. This makes the LMV301 ideal for electrometer applications requiring low input leakage such as sensitive photodetection transimpedance amplifiers and sensor amplifiers. The LMV301 also features a rail-to-rail output voltage swing in addition to a input common-mode range that includes ground. The LMV301 will drive a 600Ω resistive load and up to 1000pF capacitive load in unity gain follower applications. The low supply voltage also makes the LMV301 well suited for portable two-cell battery systems and single cell Li-Ion systems. The LMV301 exhibits excellent speed-power ratio, achieving 1...
