Analog Devices Inc./Maxim Integrated DG201AESE

Overview

DG201AESE from Maxim Integrated is a quad SPST normally closed analog switch IC designed for high-voltage signal routing in precision instrumentation and military-grade systems. It operates across ±4.5V to ±18V dual supplies, delivers 115Ω typical R_DS(ON) at ±15V, guarantees break-before-make switching, and supports -40°C to +85°C industrial temperature range in 16-pin SOIC package.

For engineers reviewing the DG201AESE datasheet, DG201AESE pinout, DG201AESE application, or DG201AESE equivalent, this page provides verified electrical parameters, validated pin functions, confirmed analog signal handling capability up to ±15V, and real-world substitution guidance for quad SPST CMOS switch selection in high-reliability analog signal paths.

Technical Context

The DG201AESE implements monolithic CMOS architecture with integrated level-shifting logic, enabling TTL/CMOS-compatible control inputs while switching bipolar analog signals. Its internal protection diodes clamp input overvoltage to V+±2V, and it remains nonlatching when power supplies are disconnected with live analog signals present.

Guaranteed break-before-make timing prevents momentary shorting during channel transitions. Switching performance is characterized at ±15V supplies: t_ON ≤ 600ns and t_OFF ≤ 450ns, with channel-to-channel crosstalk of ≥90dB and OFF-isolation ≥70dB at 100kHz.

The following parts are listed as comparable options for similar quad SPST analog switch applications.

Compared with DG201AESE, ADG201AARZ offers higher temperature resilience but higher on-resistance, while MAX4617ESE+ reduces conduction loss but sacrifices bipolar signal capability-making DG201AESE the optimal choice for ±15V dual-rail precision analog routing where robustness and rail-to-rail fidelity are critical.

FAQ

What is the maximum analog signal voltage range supported by DG201AESE?

DG201AESE supports an analog signal range of ±15V when operated with ±15V supplies. This is specified in the Electrical Characteristics table under VANALOG, and applies across the full -40°C to +85°C operating temperature range. The device maintains safe operation up to ±18V supplies, but analog signal swing remains limited to ±15V to avoid exceeding absolute maximum ratings at the S/D terminals.

Does DG201AESE require a third VL supply voltage like the original DG211?

No, DG201AESE does not require a third VL supply. Unlike the DG211, Maxim eliminated the VL pin in the DG201A family. DG201AESE operates using only V+ and V− supplies plus GND, simplifying power design and reducing external component count. This is explicitly stated in the Features section and confirmed in the Pin Description table where VL is absent.

What is the guaranteed switching speed of DG201AESE at ±15V supplies?

At ±15V supplies, DG201AESE guarantees turn-on time ≤600ns and turn-off time ≤450ns, as documented in the DG201A Electrical Characteristics table. These values are measured under standardized conditions (VS = +2V, RL = 1kΩ, CL = 35pF) and apply across the full operating temperature range for the DG201AE grade.

Is DG201AESE pin-compatible with DG211 in SOIC-16 package?

Yes, DG201AESE is pin-compatible with DG211CSE and DG211DY in 16-pin SOIC packages. Both share identical pin numbering, terminal functions (IN1–IN4, D1–D4, S1–S4, V+, V−, GND, N.C.), and mechanical footprint per MS-012. However, DG201AESE offers faster switching and eliminates the VL supply requirement - no PCB changes are needed for drop-in replacement in existing DG211 layouts.

What is the R_DS(ON) value of DG201AESE and how does it vary with supply voltage?

DG201AESE has a typical R_DS(ON) of 115Ω at ±15V supplies, with a maximum of 200Ω across temperature and process variation. As shown in the "RDS(ON) vs. Power Supplies" graph, R_DS(ON) increases significantly at lower supply voltages: e.g., ~350Ω at ±5V. Designers must verify on-resistance at their actual operating V+/V− to ensure acceptable signal attenuation in precision applications.
