Analog Devices Inc. ADG1607BCPZ-REEL7

Overview

ADG1607BCPZ-REEL7 from Analog Devices is a 8-channel differential analog multiplexer with 4.5 Ω typical on resistance, ±5 V / +12 V / +5 V / +3.3 V supply flexibility, and rail-to-rail signal handling up to ±8 V dual or 16 V single supply. It supports 3 V logic-compatible control inputs and delivers 37 MHz −3 dB bandwidth under ±5 V operation, enabling high-fidelity signal routing in precision data acquisition systems.

For engineers reviewing the ADG1607BCPZ-REEL7 datasheet, ADG1607BCPZ-REEL7 pinout, ADG1607BCPZ-REEL7 application, or ADG1607BCPZ-REEL7 equivalent, key selection criteria include differential channel count (8), on-resistance flatness (1.1 Ω typ), THD+N (0.04% typ), continuous current per channel (266 mA max at 125°C in LFCSP), and compatibility with industrial temperature range (−40°C to +125°C).

Technical Context

The ADG1607BCPZ-REEL7 implements a 3-bit binary decoder (A0–A2) to select one of eight differential source pairs (S1A/S1B through S8A/S8B) to a common differential output (DA/DB). Its iCMOS® process enables ultralow power consumption (≤1 µA IDD) while maintaining low charge injection (6–33 pC) and high off isolation (−62 dB typ at 1 MHz).

It operates without a separate VL logic supply, accepts 3 V logic inputs (VINH = 2.0 V min, VINL = 0.8 V max), and supports break-before-make switching (tBBM = 40–74 ns) across all supply configurations - critical for preventing momentary shorts in automated test equipment and relay-replacement applications.

FAQ

What supply voltages does the ADG1607BCPZ-REEL7 support?

The ADG1607BCPZ-REEL7 supports ±3.3 V to ±8 V dual supplies and 3.3 V to 16 V single supplies. At ±5 V, it achieves 4.5 Ω typical on resistance and 37 MHz −3 dB bandwidth. The device requires no separate VL logic supply - its 3 V logic-compatible inputs (VINH = 2.0 V min) interface directly with microcontrollers and FPGAs without level shifters. This flexibility simplifies power architecture in mixed-voltage systems.

How many differential channels does the ADG1607BCPZ-REEL7 provide?

The ADG1607BCPZ-REEL7 provides exactly eight differential channels, each consisting of a matched source pair (e.g., S1A/S1B) routed to a common differential output (DA/DB) via 3-bit binary address decoding (A0–A2). Unlike the ADG1606 (16 single-ended channels), the ADG1607BCPZ-REEL7 is specifically designed for noise-immune differential signal routing - critical in ECG, audio, and precision sensor interfaces where common-mode rejection matters.

What is the maximum continuous current per channel for the ADG1607BCPZ-REEL7?

The ADG1607BCPZ-REEL7 supports up to 266 mA continuous current per channel at +125°C when mounted in its native 32-lead LFCSP package (θJA = 46°C/W). This rating applies under 12 V single-supply conditions. At ±5 V dual supply and 25°C, the limit rises to 280 mA. These values are validated in Table 6 of the datasheet and reflect thermal limits - exceeding them risks junction overheating and reliability degradation.

Does the ADG1607BCPZ-REEL7 require a separate logic supply voltage (VL)?

No, the ADG1607BCPZ-REEL7 does not require a separate VL logic supply. Its digital inputs (A0, A1, A2, EN) are fully 3 V logic-compatible, with VINH specified at 2.0 V minimum and VINL at 0.8 V maximum - compatible with standard 3.3 V or 5 V GPIOs. This eliminates the need for an auxiliary logic rail, reducing system complexity, BOM cost, and PCB area. The internal iCMOS® architecture enables this integration without compromising analog performance.

What is the THD + Noise performance of the ADG1607BCPZ-REEL7?

The ADG1607BCPZ-REEL7 delivers 0.04% typical total harmonic distortion plus noise (THD+N) at 20 Hz–20 kHz with a 5 V p-p signal into 110 Ω, measured under ±5 V dual-supply conditions. This specification is confirmed in Table 1 and Figure 36 of the datasheet. Such low distortion makes the ADG1607BCPZ-REEL7 suitable for high-fidelity audio routing, medical waveform digitization, and precision test equipment where signal purity is essential.
