DESCRIPTIO

LTCMOS is a trademark of Linear Technology Corporation.

The LTC

lowpass filter with no DC error. Its unusual architecture

puts the filter outside the DC path so DC offset and low

frequency noise problems are eliminated. This makes the

LTC1062 very useful for lowpass filters where DC accuracy

is important.

The filter input and output are simultaneously taken across

an external resistor. The LTC1062 is coupled to the signal

through an external capacitor. This RC reacts with the

internal switched capacitor network to form a 5th order

rolloff at the output.

The filter cutoff frequency is set by an internal clock that

can be externally driven. The clock-to-cutoff frequency

ratio is typically 100:1, allowing the clock ripple to be

easily removed.

Two LTC1062s can be cascaded to form a 10th order quasi

max flat lowpass filter. The device can be operated with

single or dual supplies ranging from ±2.5V to ±9V.

The LTC1062 is manufactured using Linear Technology’s

enhanced LTCMOS
