Analog Devices Inc./Maxim Integrated MAX4516CSA

Overview

MAX4516CSA 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 MAX4516CSA datasheet, MAX4516CSA pinout, MAX4516CSA application, or MAX4516CSA equivalent, key selection criteria include guaranteed low on-resistance flatness (6Ω), fast switching (t_ON = 100ns), charge injection ≤20pC, and SOT23-5 package compatibility with space-constrained portable designs.

Technical Context

The MAX4516CSA uses a dual-supply CMOS architecture with V+ and V− pins powering both analog switch elements and internal logic-level translators. Its NO configuration means the COM–NO path is open when IN is low and closed when IN is high, with logic thresholds referenced to V+ (VIH = V+ − 1.5V, VIL = V+ − 3.5V).

All analog terminals (COM, NO, NC) support rail-to-rail signals, and internal ESD diodes clamp voltages exceeding V+ or V−. Leakage currents originate from reverse-biased ESD diodes to V+ or V−, not between signal paths - ensuring isolation integrity and predictable off-state behavior up to 250MHz in 50Ω systems.

Compared with MAX4516CSA, MAX4514CSA eliminates the need for a negative supply but sacrifices dual-rail flexibility, while ADG1219BRMZ trades on-resistance performance for broader temperature coverage and different packaging - neither is pin-compatible, requiring PCB redesign.

Manufacturer

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

The MAX4516/MAX4517 family was engineered specifically for low-voltage, low-leakage, rail-to-rail analog switching in portable and space-constrained systems - prioritizing on-resistance consistency, charge injection control, and dual-supply flexibility.

FAQ

What is the operating temperature range for MAX4516CSA?

The MAX4516CSA is rated for operation from 0°C to +70°C. This commercial-grade temperature range is validated for use in consumer electronics, portable instruments, and non-industrial embedded systems where ambient conditions remain within standard room-temperature envelopes. The 'C' suffix in MAX4516CSA explicitly denotes this 0°C to +70°C specification, distinct from extended-range variants like MAX4516ESA (−40°C to +85°C).

Does MAX4516CSA support single-supply operation?

No, MAX4516CSA requires dual supplies (V+ and V−) and is not specified for single-supply use. While it may function with a single positive rail and ground, its logic thresholds, leakage behavior, and guaranteed parameters (e.g., R_ON, off-isolation) are characterized only under dual-supply conditions from ±1V to ±6V. For true single-supply designs, Maxim recommends the pin-compatible MAX4514CSA instead.

What is the maximum analog signal voltage the MAX4516CSA can handle?

The MAX4516CSA supports rail-to-rail analog signals, meaning it passes voltages from V− to V+ without clipping. With ±5V supplies, the allowable analog range is −5V to +5V. Exceeding V+ or V− on any analog pin activates internal ESD diodes, limiting absolute maximum analog voltage to (V− − 0.3V) to (V+ + 0.3V) per Absolute Maximum Ratings - so sustained operation must stay strictly within the supply rails.

Is MAX4516CSA pin-compatible with other variants in the MAX4516/MAX4517 family?

Yes, MAX4516CSA shares identical pinout and functionality with all SOT23-5 packaged MAX4516 variants (e.g., MAX4516CUK, MAX4516EUK) and is functionally interchangeable with MAX4517SOT variants except for the NO/NC state inversion. All SOT23-5 versions use the same 5-pin layout: IN, NO/NC, V−, V+, COM - confirmed by Maxim's official pin configuration diagrams and marking codes (AG = MAX4516).

How does charge injection in MAX4516CSA affect ADC sampling accuracy?

MAX4516CSA's guaranteed maximum charge injection of 20pC directly impacts ADC sampling accuracy by inducing a voltage step ΔV = Q/C_L on the sampling capacitor. For a 1000pF hold capacitor, this yields ≤20mV glitch - manageable in 12-bit systems but potentially problematic in 16-bit+ designs. System-level mitigation includes using smaller C_L, adding reset pulses, or selecting switches with <5pC injection for metrology-grade applications.
