LMx58-N Low-Power, Dual-Operational
Amplifiers
1 Features
Available in 8-bump DSBGA chip-sized package (see AN-1112, SNVA009)
Internally frequency compensated for unity gain Large DC
voltage gain: 100 dB Wide bandwidth (unity gain): 1 MHz (temperature
compensated) Wide power supply range:
– Single supply: 3 V to 32 V – Or dual supplies: ±1.5 V to ±16 V Very low supply current drain (500 μA) essentially independent of supply
voltage Low input offset
voltage: 2 mV Input common-mode
voltage range includes ground Differential input
voltage range equal to the power supply
voltage Large output
voltage swing Unique characteristics:
– In the Linear Mode the input common-mode
voltage range includes ground and the output
voltage can also swing to ground, even though operated from only a single power supply
voltage
– The unity gain cross frequency is temperature compensated
– The input bias current is also temperature compensated
Advantages:
– Two internally compensated op amps – Eliminates need for dual supplies – Allows direct sensing near GND and VOUT also
goes to GND – Compatible with all forms of logic – Power drain suitable for battery operation
2 Applications
Active filters General signal conditioning and amplification 4-mA to 20-mA current loop transmitters
