Replacement verdict
Compatible functional replacement candidate
The ADG732BCPZ and ADG732BCP are functionally equivalent CMOS analog multiplexers sharing identical channel count, switch architecture, and electrical characteristics; the only distinction is the package finish, where the BC PZ suffix denotes a RoHS-compliant lead-frame finish versus the non-RoHS BC P version. The ADG732BCPZ is a valid functional replacement candidate for the ADG732BCP, with the primary consideration being RoHS compliance requirements rather than electrical or functional differences.

Key electrical and mechanical differences between the two devices
| Parameter | ADG732BCPZ | ADG732BCP | Why it matters |
|---|---|---|---|
| Number of Channels | 32 | 32 | Defines the multiplexer array size; both provide 32:1 or dual 16:1 switching, so channel count is functionally equivalent. |
| Switch Configuration | 32:1 Mux | 32:1 Mux | Determines the switching topology; identical configuration ensures direct functional substitutability in the signal path. |
| On-Resistance (Typical) | 4 Ω | 4 Ω | Low on-resistance minimizes signal attenuation and voltage drop; matching values preserve analog signal integrity. |
| Supply Voltage Range | ±2.5 V to ±5.5 V (dual), 2.5 V to 5.5 V (single) | ±2.5 V to ±5.5 V (dual), 2.5 V to 5.5 V (single) | Defines compatible power rails; identical ranges allow the parts to be used in the same circuit without supply redesign. |
| Package / Mounting | 48-Lead LFCSP (CP-48-1), Surface Mount | 48-Lead LFCSP (CP-48-1), Surface Mount | Package and footprint must match for board-level drop-in replacement; identical LFCSP ensures physical compatibility. |
| RoHS / Lead-Free Status | RoHS Compliant, Lead-Free | Non-RoHS, Contains Lead | The "Z" suffix denotes lead-free/RoHS compliance; this affects regulatory compliance and solder process compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Determines environmental suitability; identical ranges ensure the parts can be interchanged across the same application conditions. |
| Channel-to-Channel Matching | 0.5 Ω (typical) | 0.5 Ω (typical) | Matching affects differential signal accuracy; identical matching preserves precision in multiplexed measurement systems. |
| Switching Time (tON/tOFF) | 70 ns / 60 ns (typical) | 70 ns / 60 ns (typical) | Switching speed impacts throughput and timing; identical values ensure equivalent dynamic performance in the target design. |

Frequently asked questions
What is the difference between ADG732BCPZ and ADG732BCP?
The ADG732BCPZ and ADG732BCP are functionally identical 32-channel analog multiplexers. The primary difference is the suffix: the "Z" designation in ADG732BCPZ indicates RoHS-compliant lead-free packaging, while ADG732BCP is the non-RoHS version. Both are supplied in a 48-lead LFCSP package.
Are ADG732BCPZ and ADG732BCP pin-compatible?
Yes. Both devices are offered in the same 48-lead LFCSP (CP-48) package with identical pin assignments and footprint, so they are pin-compatible and can be used interchangeably on the same PCB layout.
What are the key specifications of the ADG732 multiplexer?
The ADG732 is a 32-channel, single-ended analog multiplexer with a typical on-resistance of 4 Ω, a supply range of ±2.5 V to ±5.5 V dual or 2.5 V to 5.5 V single supply, low leakage current, and CMOS/TTL-compatible logic inputs. It is controlled via a 5-bit binary address plus an enable input.
Can ADG732BCP be used as a drop-in replacement for ADG732BCPZ?
Electrically and mechanically, yes, since both share the same die, package, and pinout. However, ADG732BCP is the non-RoHS variant, so it should not be substituted in designs or markets that require RoHS compliance. For RoHS-restricted applications, use ADG732BCPZ.
What is the operating temperature range for these devices?
Both ADG732BCPZ and ADG732BCP are specified for the industrial temperature range of −40 °C to +85 °C, as stated in the Analog Devices datasheet.
Which applications are the ADG732BCPZ and ADG732BCP suited for?
These multiplexers are intended for signal routing in data acquisition systems, medical instrumentation, automatic test equipment, audio/video switching, and communication systems where low on-resistance and low leakage are required across many channels.
Do ADG732BCPZ and ADG732BCP differ in electrical performance?
No. The electrical parameters—on-resistance, leakage, switching times, supply range, and logic thresholds—are identical between the two variants. The only documented difference is the RoHS/lead-free status indicated by the "Z" suffix.
