AD5675R TSSOP-20 Pinout

Notes

• Pin numbers extracted directly from the TSSOP pin configuration diagram (top view).
• AD5675R is a 16-channel DAC variant with outputs VOUT1–VOUT9 and additional outputs on pins 11, 12, 19, 20.
• VLOGIC and VDD are separate supply pins; VLOGIC powers the digital logic while VDD powers the analog circuitry.
• GAIN, A0, A1, and RSET/SEL are configuration inputs for gain selection and I²C address assignment.

VDD = 2.7 V to 5.5 V, RL = 2 kΩ to GND, CL = 200 pF to GND, 1.62 V ≤ VLOGIC ≤ 5.5 V, all specifications TA = -40°C to +125°C, unless otherwise noted.

Thermal performance is directly linked to printed circuit board (PCB) design and operating environment. Careful attention to PCB thermal design is required.
