Product Overview

LTC1569-7 is a linear phase, DC accurate, tunable, 10th order low pass filter. This device is the first sampled data filter which does not require an external clock yet its cut-off frequency can be set with a single external resistor with a typical accuracy of 3.5% or better. The external resistor programs an internal oscillator whose frequency is divided by either 1, 4 or 16 prior to being applied to the filter network. Pin 5 determines the divider setting. Thus, up to three cut-off frequencies can be obtained for each external resistor value. Using various resistor values and divider settings, the cut-off frequency can be programmed over a range of seven octaves. Alternatively, the cut-off frequency can be set with an external clock and the clock-to-cut-off frequency ratio is 32:1. It is used in application such as data communication filters for 3V operation, linear phase and phase matched filters for I/Q signal processing, pin programmable cut-off frequency low pass filters etc.
  • One external R sets cut-off frequency, root raised cosine response
  • DC accurate, VOS(MAX) = 5mV
  • Low power modes, differential or single-ended inputs
  • Operates from 3V to ±5V supplies
  • Upto 300KHz cut-off on a single 5V supply, upto 150KHz cut-off on a single 3V supply
  • Total harmonic distortion is 74dB typical at (IN = 10KHz, 1.5VP-P)
  • Wideband noise is 125µVRMS typical
  • Power supply current is 6mA typical at (fCLK = 1.028MHz)
  • Operating temperature is 0°C to 70°C
  • Package style is 8-lead plastic narrow SO
