Product details
Overview
MAX312LCPE+ from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in ±15V or +12V systems. It delivers 10Ω max on-resistance, 1.5Ω max on-resistance matching between channels, and +3V logic-compatible inputs (VIH = 2.0V, VIL = 0.8V), enabling direct interface with low-voltage microcontrollers in test equipment and audio routing applications.
For engineers reviewing the MAX312LCPE+ datasheet, MAX312LCPE+ pinout, MAX312LCPE+ application, or MAX312LCPE+ equivalent, key selection considerations include rail-to-rail analog signal handling (±15V dual or +4.5V to +36V single supply), guaranteed RON flatness (≤2Ω over signal range), low leakage (±2.5nA at +85°C), and crosstalk >96dB at 20kHz - all verified for the 16-pin Plastic DIP package.
Technical Context
The MAX312LCPE+ implements a CMOS-based SPST switch architecture with four independent normally closed channels, each featuring matched transistor pairs to ensure ≤1.5Ω RON mismatch across temperature (–40°C to +70°C). Its logic inputs tolerate +3V TTL/CMOS levels regardless of supply configuration, eliminating level-shifting circuitry when interfacing with modern controllers.
It supports true rail-to-rail analog signal switching from V– to V+, with guaranteed operation over ±4.5V to ±20V dual supplies or +4.5V to +36V single supply. The device exhibits low charge injection (±30pC) and minimal THD (<0.01% at 1kHz, RL = 100kΩ), making it suitable for high-fidelity audio and precision data-acquisition paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 10Ω max - ensures minimal voltage drop and signal attenuation in low-impedance signal paths (e.g., audio line drivers, sensor front-ends). |
| RON match between channels | 1.5Ω max - enables precise channel-to-channel gain matching in multi-path instrumentation and balanced signal routing. |
| Analog signal range | V– to V+ - supports full-rail switching without clipping in ±15V op-amp circuits or +12V industrial I/O modules. |
| Logic compatibility | +3V compatible (VIH = 2.0V, VIL = 0.8V) - interfaces directly with 3.3V FPGA GPIOs or MCU outputs without external translators. |
| Off-leakage current | ±2.5nA at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor multiplexing applications. |
| Crosstalk | >96dB at 20kHz - prevents audible inter-channel bleed in professional audio matrix switchers. |
| Turn-on/turn-off time | 275ns / 235ns max (dual-supply) - supports fast multiplexing in automated test equipment scanning up to ~1MHz. |
Pinout & Package
MAX312LCPE+ is housed in a 16-pin Plastic DIP package (P16-2), through-hole mountable with 0.300" wide body and standard 0.1" pin pitch. Pin 1 is top-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1, IN2, IN3, IN4 | Active-low logic inputs controlling NC switch state; logic '0' closes path, '1' opens. |
| 2, 7, 10, 15 | COM1, COM2, COM3, COM4 | Analog common terminals - bidirectional signal ports connected to NC contacts when enabled. |
| 3, 6, 11, 14 | NC1, NC2, NC3, NC4 | Normally closed analog terminals - shorted to respective COM pins when INx = 0. |
| 4 | V− | Negative analog supply input; tie to GND for single-supply operation (+4.5V to +36V). |
| 5 | GND | Digital/analog reference ground - must be low-impedance connection for noise-sensitive routing. |
| 12 | N.C. | No internal connection - leave unconnected; no routing or grounding required. |
| 13 | V+ | Positive analog supply input - sets upper rail for analog signal range and powers internal logic. |
Key Features
| Feature | Design Value |
|---|---|
| +3V logic-compatible inputs | Enables direct interface with 3.3V microcontrollers and FPGAs without level shifters or pull-up resistors. |
| Rail-to-rail signal handling | Supports analog signals spanning full V− to V+ range - critical for ±12V op-amp circuits and industrial sensor conditioning. |
| Guaranteed RON flatness (≤2Ω) | Maintains consistent gain and linearity across entire analog input range - essential for precision measurement multiplexing. |
| Low crosstalk (>96dB @ 20kHz) | Prevents audible interference between adjacent audio channels in mixing consoles and broadcast routers. |
| Power-supply sequencing-free operation | Eliminates strict V+/V− power-up order requirements - simplifies power management in multi-rail systems. |
Applications
| Test Equipment Signal Routing | Professional Audio Matrix Switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG411DN | Pin-compatible but higher RON (35Ω typ), wider temp range (–40°C to +85°C), no +3V logic guarantee. | Requires external level-shifting for 3.3V control; less suitable for low-distortion audio due to higher THD. | Select DG411DN only if extended temperature operation is mandatory and RON tolerance >30Ω is acceptable. |
| MAX312CPE+ | Legacy version with VL pin; requires strict V+, VL, V− sequencing; same RON and package. | Not recommended for new designs due to latch-up risk and layout complexity from sequencing constraints. | MAX312LCPE+ replaces MAX312CPE+ with sequencing freedom and identical footprint - upgrade without PCB change. |
Compared with DG411DN and MAX312CPE+, the MAX312LCPE+ uniquely combines +3V logic compatibility, sequencing-free operation, and guaranteed RON matching - delivering lower system cost and higher reliability in 3.3V-controlled industrial and audio systems.

FAQ
What is the maximum analog signal voltage range supported by the MAX312LCPE+?
The MAX312LCPE+ supports analog signals from V− to V+, covering ±4.5V to ±20V in dual-supply mode or 0V to +36V in single-supply mode. For example, with ±15V supplies, it switches signals from –15V to +15V without clipping or distortion - confirmed in the Electrical Characteristics table under "Analog Signal Range" for dual-supply conditions.
Is the MAX312LCPE+ pin-compatible with older MAX312 variants?
Yes, the MAX312LCPE+ is pin-compatible with the legacy MAX312CPE+ and industry-standard DG411/DG412/DG413 devices in the 16-pin DIP package. Pin functions, spacing, and thermal pad absence (unlike QFN variants) are identical - enabling drop-in replacement without PCB modification, as explicitly stated in the "Features" section of the datasheet.
Does the MAX312LCPE+ require specific power-supply sequencing during startup?
No, the MAX312LCPE+ eliminates power-supply sequencing requirements. Unlike the older MAX312CPE+, it has no VL pin and operates safely regardless of V+ or V− ramp order. This is confirmed in the "Applications Information" section titled "Power-Supply Sequencing-Free Operation", which states users may apply any power-up sequence without risk of latch-up.
What is the typical on-resistance flatness specification for the MAX312LCPE+?
The MAX312LCPE+ guarantees on-resistance flatness of ≤2Ω maximum over its specified analog signal range, defined as the difference between max and min RON measured at VCOM = –5V, 0V, and +5V (dual supply) or +2V, +6V, +10V (single supply). This value ensures consistent gain and minimal harmonic distortion across the full signal swing.
Can the MAX312LCPE+ be used in single-supply +12V systems?
Yes, the MAX312LCPE+ operates fully in single-supply mode from +4.5V to +36V. With V+ = +12V and V− tied to GND, it supports analog signals from 0V to +12V and maintains 35Ω max RON (per Electrical Characteristics - Single Supply table), while retaining +3V logic compatibility and <2.5nA leakage at +85°C - validated across the full temperature range.
