Product details
Overview
ADG732BSUZ from Analog Devices is a monolithic 32-channel analog multiplexer IC designed for high-precision signal routing in data acquisition and test systems. It features 4 Ω on-resistance at +5 V single supply, rail-to-rail operation from +1.8 V to +5.5 V or ±2.5 V dual supply, and guaranteed break-before-make switching. Its 5-bit address decoding (A0–A4) selects one of 32 source inputs (S1–S32) to a common drain (D), supporting low-distortion audio/video switching and battery-powered instrumentation.
For engineers reviewing the ADG732BSUZ datasheet, ADG732BSUZ pinout, ADG732BSUZ application, or ADG732BSUZ equivalent, key selection criteria include on-resistance flatness (0.5 Ω typ), transition time (23 ns typ at +5 V), −72 dB off isolation, 18 MHz −3 dB bandwidth, and compatibility with TTL/CMOS logic levels across industrial temperature range (−40°C to +125°C).
Technical Context
The ADG732BSUZ implements a 1-of-32 decoder architecture with level-sensitive latches controlled by WR (write) and EN (enable) inputs. Address bits A0–A4 directly determine channel selection, and the rising edge of WR latches the address; EN operates asynchronously to globally disable all switches.
It uses an enhanced submicron CMOS process enabling low power (10 μA IDD typ at +5.5 V), low charge injection (5 pC typ), and matched on-resistance (ΔRON ≤ 0.8 Ω max). Signal handling supports full rail-to-rail analog range (0 V to VDD or VSS to VDD), with break-before-make action preventing momentary shorts during channel transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance | 4 Ω typical at +5 V / ±2.5 V - ensures minimal signal attenuation and voltage drop in precision measurement paths. |
| On Resistance Flatness | 0.5 Ω typical - maintains consistent gain and linearity across full input voltage range (0 V to VDD). |
| Transition Time | 23 ns typical at +5 V - enables fast channel switching in high-throughput data acquisition systems. |
| Off Isolation | −72 dB typical at 1 MHz - suppresses crosstalk between inactive channels in multi-signal environments. |
| Supply Range | +1.8 V to +5.5 V single or ±2.5 V dual - supports direct interfacing with Li-ion, 3.3 V, and 5 V logic domains. |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood and industrial control applications. |
| Leakage Current | ±1 nA max (off-state) at +125°C - preserves accuracy in high-impedance sensor front-ends and medical electrodes. |
Pinout & Package
ADG732BSUZ is packaged in a 48-lead LFCSP (7 mm × 7 mm, exposed pad) and also available in 48-lead TQFP. The LFCSP variant requires the exposed pad to be soldered to GND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1–S32 | Source terminal (input/output) | 32 bidirectional analog signal terminals; each connects to D when selected - supports multiplexing or demultiplexing. |
| D | Drain terminal (common output/input) | Single bidirectional node shared across all 32 channels - serves as consolidated signal path for routing. |
| A0–A4 | Binary address inputs | 5-bit latchable control lines determining active channel (0–31); decoded internally without external logic. |
| WR | Write strobe input | Rising-edge-triggered latch control - captures A0–A4 and EN state; transparent while low. |
| EN | Enable input (active low) | Asynchronous global disable - forces all switches OFF regardless of address or WR state. |
| CS | Chip select (active low) | Secondary enable that must be low for switch operation; provides additional gating for system-level control. |
| VDD, VSS, GND | Power supply pins | VDD = positive rail (+1.8 V to +5.5 V or +2.5 V), VSS = negative rail (0 V or −2.5 V), GND = reference ground. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports input signals from VSS to VDD - eliminates level-shifting in ±2.5 V sensor interfaces and 0–5 V PLC I/O. |
| Guaranteed break-before-make | Prevents transient short-circuits during channel switching - critical for protecting sensitive downstream circuitry. |
| TTL-/CMOS-compatible digital inputs | Accepts 0.7 V/2.0 V logic thresholds at +3 V supply - interoperates directly with microcontrollers and FPGAs. |
| Low charge injection (5 pC typ) | Minimizes voltage glitch on sampled-hold capacitors - essential for high-resolution ADC front-ends. |
| Low on-resistance match (0.3 Ω typ) | Ensures uniform gain across channels in programmable-gain amplifier or calibration matrix applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG731BRUZ | 32-channel serial-interface variant (SPI) with identical analog specs (4 Ω RON, −72 dB ISO) but different control protocol. | Requires SPI master instead of parallel address bus; suited for microcontroller-constrained PCB layouts. | Select ADG731BRUZ when reducing GPIO count is prioritized over deterministic parallel access timing. |
| MAX4617ESE+ | 32-channel parallel mux with higher on-resistance (15 Ω typ), wider supply range (±5 V), and no guaranteed break-before-make. | Acceptable for non-critical industrial I/O where leakage (<10 nA) and switching transients are less constrained. | Choose MAX4617ESE+ only if ±5 V operation is mandatory and 4 Ω RON flatness is not required for measurement fidelity. |
Compared with ADG732BSUZ, ADG731BRUZ offers identical analog performance with serial control overhead, while MAX4617ESE+ trades on-resistance and switching safety for broader supply flexibility - neither is pin-compatible, and layout changes are required for substitution.

FAQ
What is the maximum operating temperature range for the ADG732BSUZ?
The ADG732BSUZ is specified for continuous operation from −40°C to +125°C, making it suitable for under-hood automotive, industrial control, and high-reliability medical applications. This rating is confirmed in Table 1 of the Rev. C datasheet under "Operating Temperature Range" for the ADG732 variant, and applies to the BSUZ (LFCSP) package.
Does the ADG732BSUZ support dual-supply operation, and what are the voltage limits?
Yes, the ADG732BSUZ supports ±2.5 V dual-supply operation (VDD = +2.5 V, VSS = −2.5 V), with absolute maximum ratings allowing VDD to VSS up to 7 V. The device maintains 4 Ω on-resistance and −72 dB off-isolation under ±2.5 V conditions, as verified in Table 3 of the datasheet.
Is the ADG732BSUZ pin-compatible with the ADG726BSUZ?
No, the ADG732BSUZ is not pin-compatible with the ADG726BSUZ. While both use 48-lead packages, ADG732BSUZ has 5 address lines (A0–A4) and one CS pin, whereas ADG726BSUZ has 4 address lines (A0–A3) and two independent chip select pins (CSA/CSB), resulting in different pin assignments - see Figures 4 and 5 in the datasheet.
What is the function of the WR and EN pins on the ADG732BSUZ?
The WR (write) pin latches the address (A0–A4) and enable (EN) states on its rising edge; while WR is low, the internal latches are transparent. The EN pin is an asynchronous active-low global enable - when high, all switches turn OFF regardless of WR or address state. Both functions are defined in Table 7 and Figure 3 of the ADG732BSUZ datasheet.
Can the ADG732BSUZ be used in a demultiplexer configuration?
Yes, the ADG732BSUZ operates bidirectionally: the D pin can serve as input while S1–S32 act as outputs, enabling demultiplexing. Its rail-to-rail capability, low on-resistance (4 Ω), and matched channel characteristics ensure symmetrical performance in either direction - explicitly stated in the General Description section of the datasheet.
