Replacement verdict
Compatible functional replacement candidate
The ADG701LBRM is a functional replacement candidate for the ADG701BRMZ, sharing the same SPDT switch configuration, CMOS logic compatibility, and MSOP-8 footprint, while offering a lower supply voltage range and reduced on-resistance for low-voltage signal routing applications. Designers should validate logic threshold levels and supply rail compatibility before substituting in existing 5 V or ±5 V designs.

Key electrical and mechanical differences between the two devices
| Parameter | ADG701BRMZ | ADG701LBRM | Why it matters |
|---|---|---|---|
| Switch Configuration | SPST (Normally Open) | SPST (Normally Open) | Both are single-pole single-throw normally-open switches, so the basic switching function is identical. |
| Number of Channels | 1 | 1 | A single channel means both parts serve the same single-signal switching role in a circuit. |
| Supply Voltage Range | 1.8 V to 5.5 V | 1.8 V to 5.5 V | Matching supply ranges allow the parts to operate in the same low-voltage systems without redesign. |
| On Resistance (Typical) | 2.5 Ω at 5 V | 2.5 Ω at 5 V | Similar on resistance ensures comparable signal attenuation and voltage drop through the switch. |
| Package / Mounting | 8-Lead MSOP (Surface Mount) | 8-Lead MSOP (Surface Mount) | Identical package and footprint allow drop-in board replacement without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +125 °C | The wider temperature range of the L version supports use in harsher or higher-temperature environments. |
| Logic Input Threshold (VINH) | 2.0 V (at 5 V supply) | 1.4 V (at 5 V supply) | A lower logic-high threshold allows the L version to interface with lower-voltage logic levels. |
| Logic Input Threshold (VINL) | 0.8 V (at 5 V supply) | 0.5 V (at 5 V supply) | A lower logic-low threshold improves compatibility with low-voltage control signals in the L version. |

Frequently asked questions
What are the key differences between the ADG701BRMZ and the ADG701LBRM?
The ADG701BRMZ and ADG701LBRM are both single SPST normally open CMOS switches in 8-lead MSOP packages. The primary documented difference is the operating supply range and logic threshold specification: the ADG701LBRM is characterized for 1.8 V to 5.5 V single-supply operation with logic-compatible thresholds for low-voltage logic, while the ADG701BRMZ is specified for 2.7 V to 5.5 V single-supply operation. Designers should confirm the exact supply and logic-level requirements against the respective Analog Devices datasheets before substituting one for the other.
Are the ADG701BRMZ and ADG701LBRM pin-compatible?
Yes. Both devices are offered in the same 8-lead MSOP (RM) package with the same pinout, so they are pin-compatible at the package level. Electrical and logic-threshold differences must still be validated for the target design.
What is the on-resistance of these switches?
Both the ADG701BRMZ and ADG701LBRM are specified with low on-resistance, typically in the range of a few ohms (approximately 3 Ω typical at 5 V supply per the Analog Devices datasheet). On-resistance varies with supply voltage and signal level, so the datasheet curves should be consulted for the specific operating conditions.
What supply voltage range does each part support?
The ADG701LBRM is specified for single-supply operation from 1.8 V to 5.5 V, making it suitable for low-voltage systems. The ADG701BRMZ is specified for single-supply operation from 2.7 V to 5.5 V. Both are CMOS analog switches and should not be operated outside the ranges stated in their respective datasheets.
Are these switches normally open or normally closed?
Both the ADG701BRMZ and ADG701LBRM are SPST normally open (NO) switches. They close when the appropriate logic level is applied to the control input and open when the control input is at the opposite logic state.
What are typical applications for the ADG701BRMZ and ADG701LBRM?
These single SPST CMOS switches are typically used for signal routing, audio and video switching, sample-and-hold circuits, battery-powered and portable instrumentation, and general-purpose analog signal switching where low on-resistance and low power consumption are required.
Can the ADG701LBRM be used as a drop-in replacement for the ADG701BRMZ?
Because both parts share the same 8-lead MSOP package and pinout, the ADG701LBRM can physically replace the ADG701BRMZ on an existing PCB. However, the designer must verify that the lower 1.8 V minimum supply and the associated logic-threshold specifications of the ADG701LBRM are compatible with the system's supply rail and control-logic levels before treating it as a functional drop-in replacement.
