Product details
Overview
MAX4528EPA from Maxim Integrated is a low-voltage, phase-reversal analog switch IC configured as a bridge-switch array for precision DC and low-frequency signal polarity inversion. It operates from ±2.7V to ±6V dual supplies or +2.7V to +12V single supply, delivers 110Ω max on-resistance (±5V), 5pC max charge injection, <100ns transition time, and supports rail-to-rail analog signals from V− to V+. It is used in chopper-stabilized amplifiers requiring matched switch paths and low leakage.
For engineers reviewing the MAX4528EPA datasheet, MAX4528EPA pinout, MAX4528EPA application, or MAX4528EPA equivalent, key selection criteria include on-resistance matching (≤7Ω), temperature-stable leakage (<20nA at +85°C), TTL/CMOS-compatible logic thresholds (0.8V–2.4V), ESD robustness (>2kV), and −40°C to +85°C industrial temperature rating.
Technical Context
The MAX4528EPA implements a fully integrated bridge configuration of four CMOS analog switches (two normally open, two normally closed), enabling true differential phase reversal without external wiring. Its internal logic-level translator drives N- and P-channel MOSFET gates with complementary V+ and V− signals, ensuring symmetrical conduction and minimized charge injection.
It features bidirectional signal routing with no ground reference for analog paths-signals are strictly bounded between V− and V+, and all leakage flows to supply rails via ESD diodes-not through GND or cross-path terminals. AC and DC symmetry are optimized specifically for ±5V operation, with performance validated across −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2.7V to ±6V dual or +2.7V to +12V single - enables flexible biasing in mixed-signal systems with legacy or low-voltage rails |
| On-Resistance (RON) | 110Ω max (±5V) - ensures minimal gain error and voltage drop in precision signal paths |
| On-Resistance Match (∆RON) | 7Ω max - critical for chopper amplifier offset cancellation and balanced modulator carrier suppression |
| Charge Injection | 5pC max - limits settling error and baseline shift during switching in high-impedance integrator circuits |
| Transition Time | <100ns (±5V) - supports stable operation up to ~100kHz carrier frequencies in demodulator applications |
| Leakage Current | 20nA max at +85°C - preserves accuracy in µA-level sensor front-ends and zero-drift architectures |
| Logic Thresholds | VINL = 0.8V, VINH = 2.4V - guarantees interoperability with both 3.3V and 5V digital controllers without level-shifting |
Pinout & Package
MAX4528EPA is housed in an 8-pin plastic DIP package (0.300" wide), with through-hole mounting and industry-standard lead pitch (0.100"). Pin 1 is marked by a notch or dot; pin numbering follows standard counter-clockwise orientation when viewing top side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 A | Analog input/output terminal | Connected to Y when IN = LOW; to X when IN = HIGH - bidirectional, rail-to-rail capable, interchangeable with B/X/Y |
| 2 B | Analog input/output terminal | Connected to X when IN = LOW; to Y when IN = HIGH - forms complementary path with A for phase reversal |
| 3 GND | Digital ground reference | Reference for logic circuitry only; analog signals have no GND path - must tie to system digital ground |
| 4 IN | Logic control input | TTL/CMOS-compatible; accepts voltages down to V− (e.g., −5V) - controls bridge state without external level translation |
| 5 V− | Negative analog supply | Defines lower analog signal limit; connect to GND for single-supply use - also powers P-channel switch gates |
| 6 Y | Analog output/input terminal | Output when IN = LOW (A→Y, B→X); output when IN = HIGH (A→X, B→Y) - symmetric with X |
| 7 X | Analog output/input terminal | Output when IN = LOW (B→X); output when IN = HIGH (A→X) - paired with Y to form balanced output pair |
| 8 V+ | Positive analog/digital supply | Powers N-channel switches and internal logic; internally tied to substrate - bypass with 0.1µF ceramic near pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Signals swing from V− to V+ with full linearity - eliminates clipping in ±5V or 3.3V data acquisition front-ends |
| Break-before-make timing | 1ns to 20ns - prevents momentary short-circuit between A/B and X/Y paths during state transitions |
| ESD protection | >2kV per Method 3015.7 - sustains handling and board-level transients without latch-up or parametric shift |
| Low supply current | 1.0µA max - enables integration into battery-powered chopper systems without compromising standby life |
| On-resistance flatness | 15Ω max (±5V) - maintains consistent gain across full analog input range, critical for precision instrumentation |
Applications
| Chopper-Stabilized Amplifiers | Balanced Modulators/Demodulators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-reversal analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4526ESA | Higher on-resistance (150Ω max @ ±5V), wider temp range (−40°C to +85°C), same pinout and function | Suitable for less demanding chopper or modulator designs where RON match <10Ω is not required | Select when cost sensitivity outweighs need for lowest RON and charge injection |
| ADG1419BRUZ | Lower on-resistance (4.7Ω typ), higher supply voltage limit (+36V), but larger 16-lead TSSOP package and no guaranteed −40°C start | Better for high-voltage industrial DAQ, but requires PCB redesign and lacks MAX4528EPA's optimized chopper symmetry | Choose only if system requires >±15V operation or sub-5Ω RON - not a drop-in replacement |
Compared with MAX4528EPA, MAX4526ESA trades 40Ω higher RON for identical footprint and temperature rating, while ADG1419BRUZ offers superior RON and voltage range at the cost of package compatibility and chopper-specific optimization - making MAX4528EPA the preferred choice for space-constrained, low-noise, industrial-grade phase reversal.

FAQ
What is the operating temperature range of the MAX4528EPA?
The MAX4528EPA is rated for −40°C to +85°C, making it suitable for industrial environments where ambient conditions exceed commercial-grade limits. This extended range is confirmed in the Ordering Information table and validated across all key parameters including leakage, RON, and transition time - unlike the C-grade (0°C to +70°C) variants.
Does the MAX4528EPA support single-supply operation?
Yes, the MAX4528EPA supports single-supply operation from +2.7V to +12V by connecting V− to GND. The device maintains rail-to-rail analog signal handling (0V to V+), and its logic inputs remain compatible with TTL/CMOS levels. However, on-resistance increases at lower voltages (e.g., 900Ω max at +3V), so design validation at target supply is recommended.
How does the MAX4528EPA achieve phase reversal?
The MAX4528EPA achieves phase reversal using an internal bridge configuration: when IN is LOW, A connects to Y and B connects to X; when IN is HIGH, A connects to X and B connects to Y. This swaps the differential output polarity without external components - enabling true signal inversion for chopper amplifiers and balanced modulators.
What is the maximum allowable analog signal voltage range for the MAX4528EPA?
The MAX4528EPA supports analog signals from V− to V+ - e.g., −5V to +5V with ±5V supplies or 0V to +5V with +5V single supply. Signals exceeding these rails are clamped by internal ESD diodes, so input voltage must stay within (V− − 0.3V) to (V+ + 0.3V) to avoid forward conduction and potential damage or increased leakage.
Is the MAX4528EPA pin-compatible with other variants in the MAX4528 family?
Yes, the MAX4528EPA shares identical pinout and functionality with MAX4528CPA, MAX4528CSA, and MAX4528CUA - differing only in temperature grade and package type (DIP vs. SO vs. µMAX). All operate with the same truth table, electrical characteristics, and layout requirements, allowing direct substitution where temperature and package constraints permit.
