Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN+ | input | Non-inverting filter input with DC gain of 1.0 to OUT; input voltages exceeding the power supplies should be avoided, and transients will not latch up if the input current is limited to 20mA. |
| 2 | IN- | input | Inverting filter input with DC gain of -1 to OUT; input voltages exceeding the power supplies should be avoided, and transients will not latch up if the input current is limited to 20mA. |
| 3 | GND | power_in | Filter reference pin, externally biased to 2V (5V supply) or 1.11V (3V supply), bypassed with a 1µF ceramic capacitor to V- in single-supply use, with biasing impedance below 2kΩ; the maximum voltage between GND and V+ should not exceed 5.5V. |
| 4 | V- | power_in | Negative supply pin (ground in single-supply operation), requiring a quality 1µF ceramic bypass capacitor to V+ placed as close to the IC as possible. |
| 5 | DIV/CLK | input | Selects the internal divider (shorted to V- for 1:1, floating for 4:1 with 100pF to V-, shorted to V+ for 16:1) when the oscillator is enabled, or acts as the external clock input when RX is shorted to V-; pin voltages beyond the supplies should be avoided and fault current limited to 40mA. |
| 6 | RX | passive | Connect an external resistor between RX and V+ to enable the internal oscillator, with a recommended range of 3.8k to 40k; shorting RX to V- disables the oscillator. |
| 7 | V+ | power_in | Positive supply pin requiring a quality 1µF ceramic bypass capacitor to V- (and an additional 0.1µF to GND in dual-supply use), with the maximum voltage difference between GND and V+ not to exceed 5.5V. |
| 8 | OUT | output | Filter output that can drive 10kΩ and/or 40pF loads, requiring a 100Ω series resistor for larger capacitive loads, and it can exceed the supplies by up to ±2V without latchup. |

## CAD (KiCad official)
- Symbol: `LTC1569IS8-6#TRPBF`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SO-8 (KiCad packages3D, STEP)
- 3D model files: `ltc1569is8-6-trpbf-etched.step` / `ltc1569is8-6-trpbf-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ltc1569is8-6-trpbf.step` / `ltc1569is8-6-trpbf.glb` are the bare package body.
