Product details
Overview
MAX383ESE+T 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 rail-to-rail signal routing in low-voltage systems. It delivers 20Ω typical on-resistance (≤35Ω max), <2Ω matched RON between channels, <5pC charge injection, and operates from ±3V to ±8V dual supplies or +3V to +15V single supply - enabling use in battery-operated audio routing and military radio front-ends.
For engineers reviewing the MAX383ESE+T datasheet, MAX383ESE+T pinout, MAX383ESE+T application, or MAX383ESE+T equivalent, key selection criteria include guaranteed RON flatness (<4Ω over full analog range), sub-2.5nA off-leakage at +85°C, break-before-make timing (10–20ns), CMOS/TTL logic compatibility, and SO-16 narrow package compatibility with DG403 footprint.
Technical Context
The MAX383ESE+T implements a monolithic silicon-gate CMOS architecture optimized for precision analog switching. Its internal topology supports true SPDT operation with independent NO/NC paths per pole, each controlled by complementary logic inputs (IN1/IN2), and features integrated protection diodes referenced to V+ and V−.
It guarantees matched on-resistance across both poles under identical bias conditions and maintains flat RON versus analog signal voltage (VCOM) - critical for minimizing harmonic distortion in sample-and-hold and audio signal-path applications. Charge injection is actively minimized via balanced transistor sizing and layout symmetry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 20Ω typical, ≤35Ω max - ensures minimal signal attenuation and gain error in precision signal chains |
| RON match between channels | <2Ω - enables accurate differential signal switching without channel-to-channel gain mismatch |
| Charge injection | <5pC - limits voltage glitch on sampled nodes, essential for high-resolution ADC input stages |
| Off-leakage current | <2.5nA at +85°C - preserves signal integrity in high-impedance sample-and-hold or sensor interfaces |
| Turn-on / turn-off time | <175ns / <100ns - supports fast multiplexing in test equipment and real-time communication systems |
| Analog signal range | V− to V+ - allows rail-to-rail AC/DC signal handling without clipping in ±5V or +5V systems |
| Supply range | ±3V to ±8V dual or +3V to +15V single - supports portable, industrial, and military power architectures |
Pinout & Package
MAX383ESE+T is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package, 3.9mm wide, with standard 1.27mm pitch and JEDEC MS-012AC compliance. Pin 13 is GND; pins 11 and 14 are V+ and V− respectively; pins 1/3/6/8 are COM terminals; pins 4/5/9/16 are NO/NC terminals; pins 10/15 are logic inputs IN1/IN2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8 (COM1–COM4) | Analog common terminal | Switched signal path hub - connects to load or source depending on logic state |
| 4, 5, 9, 16 (NO1–NO4 / NC1–NC4) | Normally open or normally closed analog terminal | Provides SPDT functionality: NO conducts when IN=high; NC conducts when IN=low |
| 10, 15 (IN1, IN2) | CMOS/TTL-compatible logic input | Controls COM1/COM3 (IN1) and COM2/COM4 (IN2); accepts 3V/5V/±3V/±5V logic levels |
| 11 (V+) | Positive analog and logic supply | Bias reference for all internal switches and input buffers; must be powered before V− and logic |
| 14 (V−) | Negative analog supply | Enables bipolar signal handling; internal protection diodes clamp to V+ and V− |
| 13 (GND) | Logic ground reference | Return path for logic inputs only; separate from analog signal ground in mixed-signal layouts |
| 2, 7, 12 (N.C.) | Not internally connected | No internal bond wire - may be left floating or tied to GND for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ - eliminates level-shifting in ±5V instrumentation and audio circuits |
| Guaranteed RON flatness | <4Ω variation across full analog range - ensures consistent THD and settling behavior in precision filters |
| Break-before-make timing | 10–20ns delay - prevents momentary short-circuit between NO and NC paths during switching |
| Low power consumption | <10µW quiescent - extends battery life in portable PBX, heads-up displays, and handheld test gear |
| Pin compatibility with DG403 | Direct footprint replacement - simplifies upgrade of legacy designs without PCB rework |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX383EPE+ | Same die, plastic DIP-16 package; higher thermal resistance (10.53mW/°C derating vs. 8.70mW/°C for SOIC) | Preferred for through-hole prototyping or legacy board upgrades where SOIC reflow is unavailable | Select MAX383EPE+ only if manual soldering or socket-based validation is required |
| ADG403BRZ | Higher RON (60Ω typ), no guaranteed RON match or flatness spec; 16-lead SOIC but non-pin-compatible pinout | Suitable for general-purpose switching where precision matching and charge injection are not critical | Choose ADG403BRZ only for cost-sensitive, non-precision applications - not a drop-in replacement |
Compared with MAX383ESE+T, MAX383EPE+ offers identical electrical performance in a through-hole package but sacrifices thermal efficiency and board-space density, while ADG403BRZ trades precision specs for lower cost and broader availability - making MAX383ESE+T optimal for high-fidelity, space-constrained, temperature-stable designs.

FAQ
What is the maximum analog signal voltage range supported by the MAX383ESE+T?
The MAX383ESE+T supports analog signals from V− to V+, enabling rail-to-rail operation. With ±5V dual supplies, it handles −5V to +5V; with +5V single supply, it handles 0V to +5V. Absolute maximum ratings allow V+ up to +17V and V− down to −17V, but sustained operation must stay within specified supply ranges to avoid damage. This capability makes MAX383ESE+T ideal for instrumentation and audio applications requiring full dynamic range utilization.
Does the MAX383ESE+T require external protection diodes for overvoltage conditions?
The MAX383ESE+T includes internal protection diodes referenced to V+ and V−, eliminating the need for external diodes in most cases. However, if power-supply sequencing cannot be guaranteed (e.g., V− powered before V+), external series diodes are recommended per Figure 1 in the datasheet. These reduce analog range by ~0.7V but preserve MAX383ESE+T's low RON and leakage performance. For +3V single-supply operation, external diodes are not advised.
Is the MAX383ESE+T pin-compatible with the DG403 analog switch?
Yes, the MAX383ESE+T is explicitly designed as a pin-compatible upgrade to the DG403, sharing identical 16-pin SOIC pinout, logic polarity, and functional mapping. This allows direct replacement in existing DG403-based designs without PCB changes. However, MAX383ESE+T improves on RON (20Ω vs. 35Ω typ), leakage (<2.5nA vs. 5nA at +85°C), and charge injection (<5pC vs. 10pC), delivering measurable performance gains in precision applications.
What is the guaranteed on-resistance match between channels for the MAX383ESE+T?
The MAX383ESE+T guarantees on-resistance match (∆RON) of less than 2Ω between its four switched channels (COM1–COM4) under identical operating conditions. This specification is tested and guaranteed across the full temperature range (−40°C to +85°C) and ensures minimal gain mismatch in differential or multi-channel signal routing - a critical requirement in precision test equipment and guidance systems where channel tracking directly impacts measurement accuracy.
Can the MAX383ESE+T operate from a single +3.3V supply?
Yes, the MAX383ESE+T supports single +3.3V operation (within +3V to +15V range). At +3.3V, typical on-resistance rises to 75Ω (max 185Ω), turn-on time extends to 400ns, and leakage remains below 0.2nA at +25°C. While performance degrades versus ±5V operation, the device retains full functionality and rail-to-rail analog range (0V to +3.3V), making MAX383ESE+T viable for low-voltage portable systems where power efficiency and supply simplicity outweigh absolute speed or RON targets.
