Analog Devices Inc./Maxim Integrated MAX4613CPE+

Overview

MAX4613CPE+ from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, designed for precision signal routing in ±4.5V to ±20V or +4.5V to +40V supply systems. It delivers 85Ω max on-resistance, 4Ω max R_ON match between channels, <5nA off-leakage at +85°C, 10pC max charge injection, and rail-to-rail analog signal handling up to ±15V - ideal for sample-and-hold circuits and audio signal routing.

For engineers reviewing the MAX4613CPE+ datasheet, MAX4613CPE+ pinout, MAX4613CPE+ application, or MAX4613CPE+ equivalent, key selection criteria include guaranteed on-resistance flatness (9Ω max), TTL/CMOS logic compatibility, low power consumption (35µW max), ESD tolerance (2000V min), and dual- or single-supply flexibility without performance compromise.

Technical Context

The MAX4613CPE+ implements four independent CMOS-based SPST switches with separate control inputs (IN1–IN4), each driving one drain (D1–D4) and source (S1–S4) pair. Two switches are NO (SW1, SW4), two are NC (SW2, SW3), enabling configurable signal path selection without external biasing.

Its architecture supports true bidirectional conduction, rail-to-rail analog voltage handling, and logic-level translation via dedicated VL pin (5V for TTL compatibility). Switching is controlled by digital inputs referenced to VL, while analog paths operate across full V+ to V− range - decoupling logic and signal domains for robust mixed-supply operation.

Key Specifications

Pinout & Package

MAX4613CPE+ uses a 16-pin plastic DIP package (0°C to +70°C operating range), with exposed substrate connection via V+ pin. Pin assignments are standardized across DIP/SO/QSOP/TSSOP variants.

FAQ

What is the maximum analog signal voltage range supported by the MAX4613CPE+?

The MAX4613CPE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of ±44V. Under standard bipolar operation (±15V supplies), it handles ±15V signals; with ±20V supplies, the full ±20V range is usable. The MAX4613CPE+ datasheet specifies guaranteed performance across ±15V analog swings at +25°C and ±14V at temperature extremes.

Does the MAX4613CPE+ require a separate logic supply, and what happens if VL is unconnected?

Yes, the MAX4613CPE+ requires VL to be actively driven - typically to +5V for TTL compatibility or to V+ for CMOS thresholds. If VL is left floating or unconnected, logic inputs become undefined, potentially causing erratic switching behavior or increased power consumption. The MAX4613CPE+ will not function reliably without a valid VL connection per its pin description and application notes.

Can the MAX4613CPE+ be used with unbalanced supplies like +24V and −5V?

Yes, the MAX4613CPE+ explicitly supports unbalanced supplies such as +24V and −5V, as confirmed in its Applications Information section. The device operates as long as the difference between V+ and V− does not exceed +44V and each supply remains within its absolute maximum rating. This capability makes the MAX4613CPE+ suitable for asymmetric power architectures in industrial control and military radios.

How does the MAX4613CPE+ achieve low charge injection, and why is it critical for sample-and-hold use?

The MAX4613CPE+ achieves ≤10pC charge injection through matched transistor geometry and optimized gate drive design, minimizing net charge transfer during switching transitions. In sample-and-hold circuits, this directly limits hold-step voltage error - a key contributor to acquisition inaccuracy. Because the MAX4613CPE+ guarantees this spec across temperature, it ensures consistent ADC input settling without recalibration in varying ambient conditions.

Is the MAX4613CPE+ pin-compatible with the DG213, and are there any layout considerations for replacement?

Yes, the MAX4613CPE+ is explicitly pin-compatible with the industry-standard DG213, sharing identical 16-pin DIP pinout, signal naming, and functional mapping. No PCB changes are required for direct replacement; however, designers should verify that the MAX4613CPE+'s lower off-leakage (<5nA vs. DG213's typical 20nA) and tighter R_ON match do not necessitate firmware or timing adjustments in legacy systems relying on older switch characteristics.
