Analog Devices Inc./Maxim Integrated DG201AESER30129

Overview

DG201AESER30129 from Maxim Integrated is a quad SPST normally closed analog switch IC designed for high-voltage signal routing in precision instrumentation and test systems. It operates over ±4.5V to ±18V dual supplies, delivers 115Ω typical R_DS(ON) at ±15V, guarantees break-before-make switching, and supports analog signal ranges from –15V to +15V - enabling use in military radios and guidance control interfaces.

For engineers reviewing the DG201AESER30129 datasheet, DG201AESER30129 pinout, DG201AESER30129 application, or DG201AESER30129 equivalent, key selection criteria include guaranteed ±18V operation, 450ns max turn-off time, no VL supply requirement, CMOS/TTL logic compatibility, and nonlatching behavior with powered-down supplies and live input signals.

Technical Context

The DG201AESER30129 implements monolithic low-power CMOS architecture with four independent SPST switches, each featuring internal protection diodes clamping inputs to V+ and V−. Its logic interface accepts standard CMOS/TTL voltage levels, and it maintains functional integrity when power supplies are disconnected while analog signals remain active.

Switching performance is characterized by 370ns–450ns turn-off (t_OFF1) and 480ns–600ns turn-on (t_ON) times under ±15V supplies, with channel-to-channel crosstalk of 90dB and OFF-isolation of 70dB - confirming suitability for high-fidelity signal path isolation in multi-channel test equipment.

FAQ

What is the maximum supply voltage range supported by DG201AESER30129?

DG201AESER30129 supports continuous operation from ±4.5V to ±18V. Absolute maximum ratings allow V+ to V− up to 44V, and individual supply rails up to ±25V. This range ensures compatibility with legacy ±15V systems and industrial ±12V designs without derating or external regulation. The DG201AESER30129 maintains specified R_DS(ON), leakage, and timing performance across this full range.

Does DG201AESER30129 require a separate VL logic supply?

No, DG201AESER30129 does not require a VL supply. Unlike earlier analog switches such as the original DG211, Maxim eliminated the third logic supply rail. DG201AESER30129 accepts standard CMOS/TTL logic levels directly referenced to GND, simplifying power architecture and reducing system component count. This feature is explicitly confirmed in the datasheet's Features section and Electrical Characteristics tables.

What is the guaranteed turn-off time for DG201AESER30129?

The guaranteed maximum turn-off time (t_OFF1) for DG201AESER30129 is 450ns under standard test conditions (V+ = +15V, V− = −15V, R_L = 1kΩ, C_L = 35pF). This value is specified across the full operating temperature range for industrial-grade variants and is validated in the Electrical Characteristics table for DG201A. DG201AESER30129 inherits this timing specification as a member of the DG201A family.

Is DG201AESER30129 pin-compatible with DG211?

No, DG201AESER30129 is not pin-compatible with DG211. Although both are 16-pin quad SPST switches, their pin functions differ: DG211 assigns pins 12 and 13 to V+ and GND respectively, whereas DG201AESER30129 places V+ on pin 13 and GND on pin 5. Pin 12 is N.C. in DG201AESER30129 but used for logic input in DG211. Direct substitution requires PCB layout revision.

What is the analog signal range specification for DG201AESER30129?

DG201AESER30129 supports an analog signal range of –15V to +15V when operated at ±15V supplies. This is guaranteed across the full temperature range and applies to all four channels simultaneously. The device maintains low distortion and consistent R_DS(ON) within this range, as verified in the VANALOG parameter table and Typical R_DS(ON) vs. Power Supplies graph in the DG201A datasheet.
