Product details
Overview
ADG751BRMZ from Analog Devices is a CMOS single-pole, single-throw (SPST) analog switch in an 8-lead MSOP package, designed for RF/video signal routing with 300 MHz –3 dB bandwidth, 15 Ω typical on-resistance at +5 V, and –75 dB off isolation at 100 MHz. It operates from +1.8 V to +5.5 V and serves as a low-power, high-isolation replacement for mechanical relays in portable instrumentation.
For engineers reviewing the ADG751BRMZ datasheet, ADG751BRMZ pinout, ADG751BRMZ application, or ADG751BRMZ equivalent, key selection criteria include its T-switch architecture for enhanced off isolation, sub-10 ns turn-on time, bidirectional signal handling up to supply rails, and RoHS-compliant 8-lead MSOP (RM-8) packaging suitable for space-constrained RF front-ends and battery-powered audio systems.
Technical Context
The ADG751BRMZ implements a three-transistor T-switch topology: two series MOSFETs in the signal path and one shunt transistor to ground, enabling simultaneous high off isolation and wide on-state bandwidth. This architecture suppresses leakage through off-state capacitance by diverting coupled signals to GND.
It supports fully bidirectional analog operation across 0 V to VDD, features TTL/CMOS-compatible digital control (VINH ≥ 2.4 V, VINL ≤ 0.8 V), and delivers <0.01 µW typical power consumption at +5 V - critical for always-on signal paths in portable communication systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 300 MHz at +5 V - enables clean switching of video baseband and sub-GHz RF signals without attenuation. |
| On-Resistance (RON) | 15 Ω typ at +5 V - minimizes insertion loss and signal distortion in precision analog paths. |
| Off Isolation | –75 dB at 100 MHz - prevents crosstalk between adjacent channels in multiplexed RF/audio systems. |
| Switching Times | tON = 9 ns, tOFF = 3 ns - supports high-speed sequencing in sample-and-hold and TDM architectures. |
| Analog Signal Range | 0 V to VDD - allows rail-to-rail AC/DC signal switching without clipping or level-shifting. |
| Supply Voltage Range | +1.8 V to +5.5 V - ensures compatibility with Li-ion battery systems (3.3 V/5 V) and low-voltage logic interfaces. |
| Charge Injection | 1 pC typ - reduces glitch-induced errors in precision ADC input conditioning and DAC output routing. |
Pinout & Package
ADG751BRMZ is housed in an 8-lead Mini Small Outline Package (MSOP, RM-8), measuring 3.0 mm × 3.0 mm × 1.1 mm, with exposed pad for thermal enhancement and JEDEC MO-187-AA compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connect | Internally unconnected; must be left floating or tied to GND per layout best practices. |
| 2 (NC) | No Connect | Internally unconnected; no electrical function or routing required. |
| 3 (NC) | No Connect | Internally unconnected; avoids unintended coupling in high-frequency layouts. |
| 4 (D) | Drain Terminal | Bidirectional analog I/O node; handles signals from 0 V to VDD with 15 Ω RON. |
| 5 (VDD) | Positive Supply | +1.8 V to +5.5 V power rail; requires local 0.1 µF ceramic decoupling to GND. |
| 6 (S) | Source Terminal | Bidirectional analog I/O node; electrically identical to D pin in T-switch configuration. |
| 7 (GND) | Ground Reference | 0 V return path for supply and signal; must connect to low-impedance ground plane. |
| 8 (IN) | Digital Control Input | CMOS/TTL-compatible logic input; drives internal switch state (IN = 0 → ON, IN = 1 → OFF). |
Key Features
| Feature | Design Value |
|---|---|
| T-switch architecture | Combines two series and one shunt MOSFET to achieve –75 dB off isolation while maintaining 300 MHz bandwidth. |
| Rail-to-rail analog operation | Supports 0 V to VDD signal swing without degradation - eliminates need for external biasing in AC-coupled paths. |
| Ultra-low power consumption | <0.01 µW typical IDD at +5 V - extends battery life in always-on portable test equipment and IoT sensor nodes. |
| Fast, low-glitch switching | 9 ns tON / 3 ns tOFF with only 1 pC charge injection - preserves signal integrity in high-resolution data acquisition. |
| Robust ESD protection | Rated for 4000 V HBM - reduces field failure risk during automated PCB assembly and handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG752BRMZ | Same T-switch architecture and RM-8 package, but inverted logic (IN = 1 → ON); otherwise identical RON, bandwidth, and isolation. | Requires complementary control signal polarity; unsuitable where existing firmware assumes active-low enable. | Select ADG752BRMZ only when logic inversion aligns with system-level timing or GPIO constraints. |
| TMUX1574RTER | 4-channel SPDT, 5.5 V max, 6.5 Ω RON, –65 dB isolation at 100 MHz; 16-pin WQFN package. | Higher channel count and lower RON, but larger footprint and reduced off isolation limit RF suitability. | Choose TMUX1574RTER for multi-channel routing where board area permits and isolation >–70 dB is not mandatory. |
Compared with ADG751BRMZ, ADG752BRMZ offers identical RF performance with inverted control logic, while TMUX1574RTER trades off isolation and package size for higher integration - making ADG751BRMZ optimal for single-path, high-isolation, space-constrained RF/audio switching.

FAQ
What is the maximum analog signal voltage range supported by the ADG751BRMZ?
The ADG751BRMZ supports analog signals from 0 V to VDD across its S and D terminals. With a supply range of +1.8 V to +5.5 V, this means it can handle rail-to-rail signals up to +5.5 V peak without clipping or damage - ideal for unipolar sensor outputs and AC-coupled video signals where DC bias alignment is critical. The ADG751BRMZ maintains consistent on-resistance and bandwidth across this full range.
Does the ADG751BRMZ require external pull-up or pull-down resistors on its IN pin?
No, the ADG751BRMZ does not require external biasing on the IN pin. Its digital input is TTL/CMOS-compatible with guaranteed logic thresholds: VINH ≥ 2.4 V (min) and VINL ≤ 0.8 V (max) at +5 V supply. The input leakage current is ±0.5 µA max, so direct connection to microcontroller GPIOs or FPGA outputs is sufficient. Adding external resistors may degrade switching speed and is unnecessary for reliable ADG751BRMZ operation.
Can the ADG751BRMZ be used in bidirectional RF signal paths?
Yes, the ADG751BRMZ is fully bidirectional: its S and D terminals are functionally interchangeable, and signal flow direction has no effect on RON, bandwidth, or isolation. This makes the ADG751BRMZ suitable for both transmit and receive paths in antenna switching, LNA bypass, or RF test fixtures - provided the signal amplitude remains within 0 V to VDD and frequency stays below 300 MHz for minimal insertion loss.
What is the thermal resistance (θJA) of the ADG751BRMZ in its MSOP package?
The ADG751BRMZ in the 8-lead MSOP (RM-8) package has a junction-to-ambient thermal resistance (θJA) of 206°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard PCB layout with a solid ground plane and proper copper pour. For continuous operation near maximum ratings, thermal design should ensure ambient temperature plus power dissipation (IDD × VDD) × θJA remains below +150°C junction limit. The ADG751BRMZ typically dissipates <0.01 µW, making thermal management straightforward.
Is the ADG751BRMZ RoHS compliant and lead-free?
Yes, the ADG751BRMZ is RoHS compliant and lead-free. Per the Ordering Guide, the "Z" suffix in ADG751BRMZ-REEL denotes RoHS-compliant packaging. The device meets EU Directive 2011/65/EU and uses matte tin lead finish with no lead content exceeding 0.1 wt%. Full compliance documentation, including material declarations and test reports, is available from Analog Devices' official product page for ADG751BRMZ.
