LTC6087/LTC6088 Dual/Quad 14MHz, Rail-to-Rail CMOS Amplifiers
FEATURES DESCRIPTION
n
Low Offset Voltage: 750µV Maximum
The LTC®6087/LTC6088 are dual/quad, low noise, low n
Low Offset Drift: 5µV/°C Maximum
offset, rail-to-rail input/output, unity-gain stable CMOS n
Input Bias Current:
operational amplifiers that feature 1pA of input bias current.
1pA (Typical at 25°C)
A 14MHz gain bandwidth and 7.2V/µs slew rate, combined
15pA (Typical at 85°C)
with low noise (10nV/√Hz) and a low 0.75mV offset, make n
Rail-to-Rail Inputs and Outputs
the LTC6087/LTC6088 useful in a variety of applications. n Gain Bandwidth Product: 14MHz The 1.05mA supply current and the shutdown mode are n CMRR: 70dB Minimum ideal for signal processing applications which demand n PSRR: 93dB Minimum performance with minimal power. n Input Noise Voltage Density: 12nV/√Hz The LTC6087/LTC6088 has an output stage which swings n Supply Current: 1.05mA per Amp within 30mV of either supply rail to maximize signal dy- n Shutdown Current: 2.3µA per Amp namic range in low supply applications. The input common n 2.7V to 5.5V Operation Voltage mode range includes the entire supply voltage. These op n Available in 8-Lead MSOP and 10-Lead DFN amps are specified on power supply voltages of 3V and Packages (LTC6087), 16-Lead SSOP and DFN 5V from –40°C to 125°C.
