Analog Devices Inc./Maxim Integrated MAX4516EPA+

Overview

MAX4516EPA+ from Maxim Integrated is a single-pole/single-throw (SPST), normally-open (NO), CMOS analog switch optimized for low-voltage dual-supply operation. It delivers 20Ω on-resistance at ±5V, 1nA off-leakage at +25°C, and rail-to-rail signal handling across ±1V to ±6V supplies-enabling precision signal routing in battery-powered audio and data-acquisition systems.

For engineers reviewing the MAX4516EPA+ datasheet, MAX4516EPA+ pinout, MAX4516EPA+ application, or MAX4516EPA+ equivalent, key selection criteria include guaranteed on-resistance flatness (6Ω), fast switching (t_ON = 100ns), low charge injection (20pC max), and SOT23-5 package compatibility with space-constrained portable designs.

Technical Context

The MAX4516EPA+ uses complementary CMOS transistor pairs driven by V+ and V− to achieve bidirectional, rail-to-rail analog conduction without ground reference. Its logic input is referenced to V+, supporting CMOS-compatible thresholds (VIH = V+ − 1.5V, VIL = V+ − 3.5V) across ±5V supplies.

Internal ESD diodes clamp analog pins to V+ and V−, making leakage current highly dependent on signal voltage relative to supply rails. Off-isolation reaches −86dB at 100kHz, while on-capacitance (22pF) and off-capacitance (9pF) ensure minimal signal distortion up to 250MHz in 50Ω systems.

Key Specifications

Pinout & Package

MAX4516EPA+ is housed in an industry-standard 5-pin SOT23-5 package (JEDEC MO-178AA), with exposed pad not connected. Pin 1 is marked via laser etch "AG" for MAX4516 identification.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power-management ICs for demanding industrial, medical, and communications applications.

The MAX4516/MAX4517 family was engineered specifically for low-distortion, low-leakage analog switching in portable and dual-supply systems-prioritizing on-resistance consistency, charge injection control, and wide supply flexibility over raw speed or integration density.

FAQ

What is the operating temperature range for MAX4516EPA+?

The MAX4516EPA+ is rated for operation from −40°C to +85°C, making it suitable for industrial and extended-temperature consumer applications. This grade exceeds the commercial 0°C to +70°C range of the MAX4516CPA+ variant and is validated per Maxim's E-grade qualification standards, including temperature cycling and long-term reliability testing at maximum junction temperature.

Does MAX4516EPA+ support single-supply operation?

No-MAX4516EPA+ is designed exclusively for dual-supply operation (±1V to ±6V). It lacks a ground reference and relies on symmetric or asymmetric V+ and V− rails to bias internal CMOS switches and logic translators. For single-supply use, Maxim recommends the pin-compatible MAX4514 series, which features different threshold architecture and supply pinning.

What is the maximum analog signal voltage that can be applied to MAX4516EPA+?

The MAX4516EPA+ supports rail-to-rail analog signals from V− to V+, meaning the full analog range equals the difference between its negative and positive supply voltages. With ±5V supplies, signals from −5V to +5V are fully supported; exceeding V+ or V− triggers internal ESD diode conduction, limiting safe continuous input to within −0.3V to (V+ + 0.3V) per Absolute Maximum Ratings.

How does charge injection affect system performance in MAX4516EPA+ applications?

Charge injection of up to 20pC in MAX4516EPA+ causes a transient voltage glitch (∆V = Q/C_L) on the COM node when the switch turns OFF. In a 1000pF sampling capacitor, this yields ≤20mV error-critical in precision ADC sample-hold stages. System-level mitigation includes minimizing load capacitance, using guard traces, and synchronizing switching with ADC conversion timing to avoid sampling during transients.

Is MAX4516EPA+ pin-compatible with other variants in the MAX4516 family?

Yes-MAX4516EPA+ shares identical pinout and functionality with all SOT23-5 packaged MAX4516 variants (e.g., MAX4516CUK, MAX4516EUK). The "E" suffix denotes −40°C to +85°C temperature grade, while "C" and "M" denote commercial and military grades; all SOT23-5 versions use the same AG-marked 5-pin layout and electrical interface.
