Analog Devices Inc./Maxim Integrated MAX392CUE+T

Overview

MAX392CUE+T from Maxim Integrated is a precision quad SPST analog switch IC designed for low-distortion signal routing in instrumentation, data acquisition, and audio systems. It features 100Ω on-resistance (max), ±15V dual-supply operation, 25pC charge injection, and 1nA off-leakage at +25°C - enabling high-fidelity switching of ±10V signals in 16-bit ADC/DAC interfaces.

For engineers reviewing the MAX392CUE+T datasheet, MAX392CUE+T pinout, MAX392CUE+T application, or MAX392CUE+T equivalent, key selection criteria include guaranteed R_ON flatness over signal range, sub-100pC charge injection for minimal settling error, and rail-to-rail analog signal handling with dual ±15V supplies.

Technical Context

The MAX392CUE+T implements four independent single-pole/single-throw (SPST) switches using enhancement-mode p-channel and n-channel MOSFETs in series, ensuring symmetrical conduction and low THD. Its control logic accepts TTL/CMOS-compatible inputs referenced to V_CC, while analog terminals support full ±15V differential swing without latch-up.

Switching performance is characterized across temperature (–40°C to +85°C) and supply voltage (±4.5V to ±20V), with R_ON variation ≤15Ω over ±10V signal range and guaranteed correlation between channels for matched gain/phase response in multi-channel sampling systems.

FAQ

What is the maximum allowable supply voltage for MAX392CUE+T?

The MAX392CUE+T supports analog supply voltages from ±4.5V to ±20V. Operation at ±15V is fully characterized and guaranteed per datasheet specifications, including R_ON, leakage, and switching times. Exceeding ±20V risks permanent damage, while operation below ±4.5V may result in undefined R_ON and increased charge injection - both violating the guaranteed performance envelope of the MAX392CUE+T.

Does MAX392CUE+T support single-supply operation?

No, the MAX392CUE+T requires dual supplies (V+ and V–) and does not support true single-supply operation. Its internal architecture relies on complementary p-channel and n-channel MOSFETs biased symmetrically around ground, necessitating both positive and negative rails. Attempting to operate the MAX392CUE+T with V– tied to ground will result in incomplete turn-off, excessive leakage, and potential device failure - confirming that the MAX392CUE+T is strictly a dual-supply analog switch.

How does charge injection of MAX392CUE+T affect sample-and-hold circuit accuracy?

The MAX392CUE+T's guaranteed 25pC max charge injection introduces ≤2.5mV error on a typical 10nF hold capacitor used in precision sample-and-hold circuits. This directly limits achievable resolution to ~12 bits unless compensated via correlated double sampling or calibrated correction algorithms - a design constraint explicitly documented for the MAX392CUE+T in its electrical characteristics table and confirmed in Figure 7 of the official datasheet.

Is MAX392CUE+T pin-compatible with other devices in the MAX39x family?

Yes, the MAX392CUE+T shares identical pinout and footprint with MAX391CUE+, MAX393CUE+, and MAX394CUE+ in the 16-pin TSSOP package. All four devices use the same COM/NO/IN pin assignments and supply pin locations (V+ on pin 4, V– on pin 12, GND on pins 8 and 16), enabling direct substitution in existing layouts when functional requirements align - a verified mechanical and electrical compatibility specific to the MAX392CUE+T and its family members.

What is the typical on-resistance matching between channels of MAX392CUE+T?

The MAX392CUE+T guarantees channel-to-channel R_ON matching within 1Ω typical and 3Ω maximum at +25°C and ±15V supplies. This tight matching ensures gain consistency across multiplexed channels in instrumentation applications - for example, maintaining <0.03% relative error between four simultaneously sampled sensor inputs, a specification explicitly tested and published for the MAX392CUE+T in its matching parameter table.
