Analog Devices Inc./Maxim Integrated MAX383BCSE

Overview

MAX383BCSE from Maxim Integrated is a precision single-pole double-throw (SPDT) analog switch with two normally open (NO) and two normally closed (NC) poles, designed for low-voltage signal routing in precision instrumentation. It delivers 20Ω typical on-resistance (≤35Ω max), <2Ω matched R_ON between channels, <5pC charge injection, <2.5nA off-leakage at +85°C, and operates from ±3V to ±8V dual supplies or +3V to +15V single supply - enabling rail-to-rail analog signal handling in battery-powered test equipment and military radios.

For engineers reviewing the MAX383BCSE datasheet, MAX383BCSE pinout, MAX383BCSE application, or MAX383BCSE equivalent, key selection criteria include guaranteed R_ON flatness (<4Ω over full signal range), break-before-make timing (10–20ns), CMOS/TTL logic compatibility across 3V/5V/±3V/±5V, and verified performance in sample-and-hold circuits and audio signal routing where low distortion and channel matching are critical.

Technical Context

The MAX383BCSE implements a monolithic silicon-gate CMOS architecture optimized for low-voltage precision switching. Its internal design guarantees matched on-resistance (<2Ω delta) and flat R_ON (<4Ω variation) across the full analog signal range (V₋ to V₊), while achieving sub-175ns turn-on and sub-100ns turn-off times under 100Ω/5pF load conditions.

It supports true rail-to-rail analog signal handling with input voltage tolerance up to (V₋ − 2V) to (V₊ + 2V), features integrated protection diodes, and maintains <10µW quiescent power consumption - making it suitable for high-accuracy, low-noise signal paths in portable and thermally constrained systems.

FAQ

What is the operating temperature range for MAX383BCSE?

The MAX383BCSE is rated for 0°C to +70°C ambient operation. This commercial-grade temperature range is defined by the 'C' suffix in the part number and validated per Maxim's production test flow. The device uses a narrow SOIC package with thermal characteristics suited for board-level convection cooling in enclosed enclosures. For extended temperature applications, consider MAX383ESE (−40°C to +85°C) or MAX383MJE (−55°C to +125°C).

Does MAX383BCSE support dual-supply operation?

Yes, MAX383BCSE supports dual-supply operation from ±3V to ±8V, enabling true bipolar analog signal switching. When operated with V+ = +5V and V− = −5V, it handles analog signals from −5V to +5V rail-to-rail. Power supply sequencing must follow V+ first, then V−, then logic inputs to avoid latch-up. Internal protection diodes clamp signals exceeding V+ or V−, but sustained overvoltage requires external series diodes per Figure 1 in the datasheet.

What is the maximum analog signal voltage range supported by MAX383BCSE?

The MAX383BCSE supports analog signals from V− to V+, i.e., rail-to-rail operation. With ±5V supplies, this equals −5V to +5V; with +12V single supply, it equals 0V to +12V. Absolute maximum ratings allow signals up to (V− − 2V) to (V+ + 2V), but functional operation is guaranteed only within V− to V+. Exceeding these limits risks increased leakage or permanent damage unless external clamping is implemented.

Is MAX383BCSE pin-compatible with legacy DG-series switches?

Yes, MAX383BCSE is explicitly pin-compatible with DG403 and DG405 analog switches per Maxim's datasheet Features section. Pin assignments for COM, NO, NC, IN, V+, V−, and GND align directly - allowing drop-in replacement in existing layouts. However, note that MAX383BCSE offers superior specifications: lower R_ON (20Ω vs. 45Ω), tighter matching (<2Ω vs. ±5Ω), and lower charge injection (<5pC vs. 15pC), which may require revalidation of timing-critical paths.

What is the guaranteed on-resistance flatness specification for MAX383BCSE?

The MAX383BCSE guarantees on-resistance flatness of ≤4Ω maximum variation over its specified analog signal range (V− to V+). This parameter - defined as R_ON(max) − R_ON(min) measured across the full voltage swing - ensures consistent gain and linearity in precision attenuators, programmable gain amplifiers, and multiplexed sensor interfaces where signal-dependent resistance changes would introduce harmonic distortion or measurement error.
