Replacement verdict
Compatible functional replacement candidate
The ADG732BCPZ and ADG731BCP are both 32-channel CMOS analog multiplexers from Analog Devices in the same 48-lead LFCSP package, sharing identical supply, interface, and switching characteristics. The ADG731BCP is a functional replacement candidate for the ADG732BCPZ, with the primary distinction being the output configuration (single 32:1 multiplexer versus dual 16:1 multiplexer). Designers should confirm the channel architecture meets the target signal-routing requirement before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADG732BCPZ | ADG731BCP | Why it matters |
|---|---|---|---|
| Number of Channels | 32:1 (single-ended) | 32:1 (single-ended) | Both are 32-to-1 multiplexers, so channel count is functionally equivalent for signal routing. |
| Switch Configuration | 32:1 Multiplexer | 32:1 Multiplexer | Confirms both parts perform the same multiplexing function, supporting direct substitution. |
| On-Resistance (RON) | 4 Ω (typ) | 4 Ω (typ) | Low on-resistance minimizes signal attenuation and voltage drop across the switch. |
| Supply Voltage Range | ±2.5 V to ±5.5 V dual, or 2.5 V to 5.5 V single | ±2.5 V to ±5.5 V dual, or 2.5 V to 5.5 V single | Matching supply ranges ensure the parts are interchangeable in the same power architecture. |
| Package / Mounting | 48-Lead LFCSP (surface mount) | 48-Lead LFCSP (surface mount) | Identical package and footprint allow drop-in replacement on the same PCB layout. |
| Channel-to-Channel Matching | 0.5 Ω (typ) | 0.5 Ω (typ) | Good matching reduces gain error between channels in precision signal routing. |
| Switching Time (tON/tOFF) | tON 30 ns, tOFF 15 ns (typ) | tON 30 ns, tOFF 15 ns (typ) | Fast switching supports high-speed multiplexing and time-critical signal selection. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Same temperature range ensures equivalent environmental robustness for industrial use. |
