Product details
Overview
ADG732BCPZ-REEL from Analog Devices is a monolithic 32-channel analog multiplexer IC designed for high-fidelity signal routing in precision data acquisition and automated test equipment. 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. It routes one of 32 analog inputs (S1–S32) to a common drain (D) under 5-bit address control (A0–A4), enabling scalable channel selection in battery-powered medical instrumentation and optical switching systems.
For engineers reviewing the ADG732BCPZ-REEL datasheet, ADG732BCPZ-REEL pinout, ADG732BCPZ-REEL application, or ADG732BCPZ-REEL equivalent, key selection criteria include its 18 MHz −3 dB bandwidth, 23 ns typical transition time, 0.5 Ω on-resistance flatness, and 48-lead LFCSP package with exposed pad-critical for low-noise, space-constrained PCB layouts requiring minimal charge injection (5 pC typ) and high off-isolation (−72 dB).
Technical Context
The ADG732BCPZ-REEL implements a single 1-of-32 decoder architecture driven by five TTL-/CMOS-compatible address lines (A0–A4), with latched control via a rising-edge-triggered WR input and active-low EN/CS enable logic. Its enhanced submicron CMOS process delivers matched on-resistance across all 32 channels and tightly controlled RFLAT(ON) (0.5 Ω typ), ensuring signal integrity over full rail-to-rail input ranges.
It supports three supply configurations: +5 V ±10%, +3 V ±10%, or ±2.5 V ±10%, with leakage currents specified down to ±0.01 nA (typ) and guaranteed break-before-make action (tD = 18 ns typ at +5 V). The device operates across −40°C to +125°C, with thermal impedance θJA = 25°C/W on a 4-layer board-optimized for industrial and automotive-grade embedded signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 32-channel single-ended multiplexer: selects one of 32 analog inputs (S1–S32) to common output D. |
| On Resistance | 4 Ω typical at +5 V / ±2.5 V supply: enables low insertion loss and minimal gain error in precision sensor interfaces. |
| Supply Range | +1.8 V to +5.5 V single supply or ±2.5 V dual supply: supports portable, mixed-voltage, and bipolar signal chain designs. |
| Transition Time | 23 ns typical (RL = 300 Ω, CL = 35 pF): ensures fast channel switching for high-throughput ATE and real-time monitoring. |
| Off Isolation | −72 dB typical at 1 MHz: suppresses crosstalk between inactive channels in multi-signal routing applications. |
| Operating Temperature | −40°C to +125°C: qualified for under-hood automotive, industrial control, and extended-range medical environments. |
| Package | 48-lead LFCSP (7 mm × 7 mm, CP-48-4): thermally enhanced with exposed pad tied to GND for stable high-frequency performance. |
Pinout & Package
ADG732BCPZ-REEL uses a 48-lead Lead Frame Chip Scale Package (LFCSP), CP-48-4 variant, with an exposed thermal pad that must be soldered to a GND plane for optimal thermal and electrical performance. Pin pitch is 0.5 mm; body size is 7 mm × 7 mm × 0.85 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–12, 45–48 | S1–S16, S17–S32 | 32 analog source terminals: bidirectional I/O pins supporting input or output signal routing; grouped as two banks (S1–S16 top/bottom rows, S17–S32 middle rows). |
| 13, 14 | VDD | Positive supply pin: accepts +1.8 V to +5.5 V (single) or +2.5 V (dual); both pins must be connected to same potential. |
| 15–19 | A0–A4 | 5-bit binary address inputs: determine selected channel (0–31); CMOS/TTL compatible with VIH = 2.4 V min (+5 V), 2.0 V min (+3 V), 1.7 V min (±2.5 V). |
| 20 | CS | Active-low chip select: disables all switches when high; required for multi-device bus sharing or power gating. |
| 21 | WR | Write clock input: latches A0–A4 and EN/CS states on rising edge; level-transparent while low for dynamic reconfiguration. |
| 22 | EN | Active-low enable: globally disables all switches when high; independent of WR latch timing for safe power sequencing. |
| 23 | GND | Ground reference: primary 0 V return for digital and analog domains; must be low-impedance and decoupled. |
| 24 | VSS | Negative supply pin: connects to −2.5 V in dual-supply mode; ties to GND in single-supply operation. |
| 43 | D | Common drain/output terminal: bidirectional node where selected Sx channel connects; supports rail-to-rail signal swing. |
| 41, 42, 44 | NIC | Not internally connected: no internal bond wire; must remain unconnected and unstubbed to avoid parasitic coupling. |
| EPAD | Exposed Pad | Thermal & electrical ground: mandatory connection to PCB GND plane for thermal dissipation (θJA = 25°C/W) and noise reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports full VSS to VDD swing (e.g., −2.5 V to +2.5 V or 0 V to +5.5 V), preserving dynamic range in sensor front-ends and DAC outputs. |
| Guaranteed break-before-make switching | Prevents momentary shorting during channel transitions (tD = 18 ns typ), essential for avoiding signal glitches in relay-replacement and audio routing. |
| Low on-resistance flatness (0.5 Ω typ) | Minimizes distortion and gain variation across signal amplitude-critical for high-accuracy data acquisition and medical imaging front-ends. |
| Ultra-low leakage (±0.01 nA typ off-leakage) | Reduces measurement drift in high-impedance sensor interfaces (e.g., pH electrodes, piezoelectric transducers) and long-integration ATE fixtures. |
| Charge injection of 5 pC typical | Enables precise sampling in switched-capacitor circuits and sample-and-hold stages without significant settling error or pedestal shift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG732BRUZ | Same die, 48-lead TQFP package (10 mm × 10 mm); higher θJA = 54.6°C/W; no exposed thermal pad. | Preferred for prototyping or legacy PCBs with TQFP footprints; less suitable for thermally constrained or high-density layouts. | Select ADG732BRUZ only if TQFP compatibility or hand-soldering is required; ADG732BCPZ-REEL offers superior thermal performance and smaller footprint. |
| MAX4618ESE+ | 16-channel, not 32-channel; 6 Ω on-resistance; +2.7 V to +12 V supply; SO-16 package. | Limited to lower-channel-count, higher-voltage systems; lacks break-before-make guarantee and rail-to-rail operation. | Choose MAX4618ESE+ only for cost-sensitive, low-channel, wide-supply applications where 32-channel density and precision are not required. |
Compared with ADG732BRUZ, ADG732BCPZ-REEL delivers 45% lower thermal resistance and 30% smaller area; versus MAX4618ESE+, it provides double channel count, 33% lower on-resistance, and guaranteed break-before-make-making it the optimal choice for high-density, high-precision, thermally demanding signal routing.

FAQ
What supply voltages does the ADG732BCPZ-REEL support?
The ADG732BCPZ-REEL supports +1.8 V to +5.5 V single supply (with VSS tied to GND) or ±2.5 V dual supply (VDD = +2.5 V, VSS = −2.5 V). It is fully specified and guaranteed at +5 V ±10%, +3 V ±10%, and ±2.5 V ±10%. Operation outside these rails violates absolute maximum ratings and may cause permanent damage.
Does the ADG732BCPZ-REEL require external pull-up or pull-down resistors on its digital inputs?
No, the ADG732BCPZ-REEL has TTL-/CMOS-compatible digital inputs (A0–A4, EN, CS, WR) with defined VIH and VIL thresholds-no external biasing is needed. For example, at +5 V supply, VIH ≥ 2.4 V and VIL ≤ 0.8 V; input current remains ±0.5 μA max, eliminating need for pull resistors in standard microcontroller interfacing.
How is channel selection implemented in the ADG732BCPZ-REEL?
Channel selection in the ADG732BCPZ-REEL is performed via five address inputs (A0–A4), decoded into a 1-of-32 selection. The selected channel connects Sx to D on the rising edge of WR, provided EN and CS are low. Address changes while WR is low are transparent; latching occurs only on WR's positive transition.
Is the ADG732BCPZ-REEL pin-compatible with the ADG726?
No-the ADG732BCPZ-REEL (32-channel) and ADG726 (dual 16-channel) have different pin functions and truth tables. ADG726 uses separate CSA/CSB and A0–A3, while ADG732BCPZ-REEL uses single CS and A0–A4. Their 48-lead LFCSP footprints share mechanical dimensions but differ electrically; PCB redesign is required for substitution.
What is the maximum signal frequency supported by the ADG732BCPZ-REEL?
The ADG732BCPZ-REEL has a −3 dB bandwidth of 18 MHz (typical, RL = 50 Ω, CL = 5 pF). This defines the upper limit for small-signal AC routing; for DC or low-frequency precision applications (e.g., sensor multiplexing), bandwidth is not limiting-on-resistance flatness and leakage dominate performance.
