Analog Devices Inc./Maxim Integrated DG507ACJ+

Overview

DG507ACJ+ from Maxim Integrated is a monolithic CMOS differential 8-channel (2-of-16) analog multiplexer with break-before-make switching, ±4.5V to ±18V dual-supply operation, 270Ω typical on-resistance at ±15V, and TTL/CMOS-compatible logic inputs. It routes bidirectional analog signals in precision data acquisition and signal routing systems requiring low leakage and symmetrical channel performance.

For engineers reviewing the DG507ACJ+ datasheet, DG507ACJ+ pinout, DG507ACJ+ application, or DG507ACJ+ equivalent, key selection criteria include its differential 8-channel architecture, guaranteed latch-up immunity with powered-off supplies, 0.6µs typical transition time, and compatibility with legacy IH6216, HI507, and DG507A designs.

Technical Context

The DG507ACJ+ implements a fully differential 2-of-16 switch matrix using monolithic CMOS process technology, supporting symmetrical bidirectional analog signal flow between eight differential pairs (S1a/S1b through S8a/S8b) and two common terminals (Da, Db). Its address decoding uses A0–A2 and A3 inputs to select one of eight differential channels.

Break-before-make timing ensures no transient shorting during channel transitions, with a guaranteed 0.2µs minimum open interval. Enable control (EN) allows global on/off gating independent of address state, while logic inputs tolerate TTL and CMOS voltage levels across the full operating temperature range (0°C to +70°C).

FAQ

What is the maximum analog signal voltage range supported by the DG507ACJ+?

The DG507ACJ+ supports an analog signal range of ±15V when operated with ±15V supplies. This range is defined by the device's absolute maximum ratings and remains valid across its full 0°C to +70°C operating temperature range. Signals beyond ±15V risk clamping by internal diodes and must be limited to stay within the specified drain-to-source voltage limits.

Does the DG507ACJ+ require external pull-up or pull-down resistors on its address inputs?

No, the DG507ACJ+ does not require external pull-up or pull-down resistors on A0–A2 or A3 inputs. Its TTL- and CMOS-compatible logic inputs have defined thresholds (0.8V low, 2.4V high) and sufficient input impedance to interface directly with microcontroller GPIO or FPGA outputs. Internal design ensures stable logic states without external biasing under normal operating conditions.

How does the break-before-make feature of the DG507ACJ+ protect downstream circuitry?

Break-before-make operation in the DG507ACJ+ guarantees a minimum 0.2µs open interval between deactivation of one differential channel and activation of the next. This prevents momentary short-circuits between analog sources - critical when routing signals from isolated sensors or mismatched impedance nodes - thereby eliminating transient current surges that could damage sensitive ADC inputs or induce measurement errors.

Can the DG507ACJ+ be used with single-supply configurations?

No, the DG507ACJ+ is designed exclusively for dual-supply operation (±4.5V to ±18V). Its internal CMOS switch architecture requires symmetric positive and negative rails to maintain linear analog conduction and specified on-resistance. Single-supply use violates absolute maximum ratings and results in undefined switching behavior, increased distortion, and potential device damage.

Is the DG507ACJ+ pin-compatible with the original Intersil IH6216?

Yes, the DG507ACJ+ is explicitly documented as a drop-in replacement for the Intersil IH6216. Both devices share identical 28-pin DIP pinouts, address decoding (A0–A2), enable logic polarity, and differential channel labeling (S1a/S1b through S8a/S8b). No PCB modifications are required when substituting DG507ACJ+ for IH6216 in existing designs.
