Analog Devices AD75019 Datasheet (Product Handbook)
The AD75019 is a 16 × 16 crosspoint switch array containing 256 analog switches that can be programmed to connect any X pin to any Y pin. It operates over a wide signal range up to the supply rails and features a typical on‑resistance of 150 Ω. Data is loaded serially via SIN and clocked into a 256‑bit shift register, then transferred to parallel latches with PCLK. The device can be cascaded for larger arrays using the SOUT output.
Key specifications include a minimum clock rate of 20 kHz, a maximum clock rate of 5 MHz, supply voltage ranges of 9.0‑25.2 V (analog) and 4.5‑5.5 V (digital), and an operating temperature range of –25 °C to +85 °C. Proper power‑supply sequencing and bypass capacitors (0.1 mF ceramic) are required to ensure reliable operation.
