DESCRIPTION
The LTC1066-1 is an 8th order elliptic lowpass filter which simultaneously provides clock-tunability and DC accuracy. The unique and proprietary architecture of the filter allows 14 bits of DC gain linearity and a maximum of 1.5mV DC offset. An external RC is required for DC accurate operation. With ±7.5V supplies, a 20k resistor and a 1µF capacitor, the cutoff frequency can be tuned from 800Hz to 100kHz. A clock-tunable 10Hz to 100kHz operation can also be achieved (see Typical Application section).
FEATURES
■ DC Gain Linearity: 14 Bits
■ Maximum DC Offset: ±1.5mV
■ DC Offset TempCo: 7µV/°C
■ Device Fully Tested at fCUTOFF = 80kHz
■ Maximum Cutoff Frequency: 120kHz (VS = ±8V)
■ Drives 1kΩ Load with 0.02% THD or Better
■ Signal-to-Noise Ratio: 90dB
■ Input Impedance: 500MΩ
■ Selectable Elliptic or Linear Phase Response
■ Operates from Single 5V up to ±8V Power Supplies
APPLICATIONS
■ Instrumentation
■ Data Acquisition Systems
■ Anti-Aliasing Filters
■ Smoothing Filters
■ Audio Signal Processing
