PRODUCT OVERVIEW

What Is the AD7606BSTZ-RL?

AD7606BSTZ-RL is a 16-bit, 8-channel simultaneous-sampling data acquisition system (DAS) from Analog Devices. The device integrates analog input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier per channel, a 16-bit charge-redistribution successive-approximation (SAR) ADC core, a flexible digital filter, a 2.5 V reference with buffer, and high-speed serial and parallel interfaces.[reference:0]

The AD7606BSTZ-RL operates from a single 5 V supply and accepts true bipolar ±10 V and ±5 V input signals without requiring external bipolar rails or driver op-amps.[reference:1] All eight track-and-hold amplifiers sample on the same CONVST edge, preserving relative phase between channels - a critical feature for energy measurement and multi-channel instrumentation applications.[reference:2]

The device features a 1 MΩ analog input impedance that is constant regardless of sampling rate, and on-chip clamp circuitry tolerates overvoltage up to ±16.5 V.[reference:3] Throughput reaches 200 kSPS on every channel, and both parallel and serial (SPI/QSPI/MICROWIRE-compatible) interfaces are available.[reference:4] The -RL suffix denotes tape-and-reel packaging with 1,500 units per reel, optimized for high-volume automated assembly.[reference:5] The AD7606BSTZ-RL is offered in a 64-lead LQFP package with a 10.00mm × 10.00mm footprint and is rated for operation from –40°C to +85°C.[reference:6] The device is in active production.[reference:7][reference:8]

Simultaneous-Sampling ADC 8 channels with true simultaneous sampling, preserving inter-channel phase relationships.

True Bipolar Inputs ±10 V and ±5 V input ranges with single 5 V supply - no external negative rails required.

Tape-and-Reel Packaging -RL suffix variant designed for high-volume automated assembly (1,500 units per reel).

Circuit Considerations for AD7606BSTZ-RL

Power Supply & Decoupling

The AD7606BSTZ-RL requires careful power supply design:

Analog Supply (AVCC): 4.75 V to 5.25 V; decouple each AVCC pin with a 100 nF capacitor plus a bulk 10 µF capacitor at the supply source[reference:19]
Logic Supply (VDRIVE): 2.3 V to 5.25 V, sets the digital interface voltage level[reference:20]
Grounding: Separate AGND and DGND references must stay within 0.3 V of each other
Reference Decoupling: The REFIN/REFOUT pin requires a 10 µF decoupling capacitor

PCB and Interface Guidance

ADC performance depends on layout and interface configuration:

Analog Inputs: Eight single-ended analog inputs (V1–V8) each pair with a dedicated analog ground return (V1GND–V8GND) to preserve signal integrity per channel
Reference Selection: REF SELECT pin chooses internal (2.5 V) or external reference
Input Range Selection: RANGE pin selects ±5 V or ±10 V full-scale input range
Interface Mode: PAR/SER SEL pin selects parallel or serial interface mode[reference:21]
Oversampling: OS0–OS2 pins configure the digital oversampling ratio
PCB Layout: Keep analog and digital domains physically separated on the PCB; the LQFP package groups pins by function to facilitate this
Verify the recommended PCB footprint from the official datasheet prior to production

REPLACEMENT GUIDANCE

Selecting an Alternative for AD7606BSTZ-RL

A replacement for the AD7606BSTZ-RL should not be selected solely by product category. The electrical characteristics, package, and pin configuration must be evaluated against the specific circuit requirements. The following alternatives are documented in the official Analog Devices product pages and datasheets.

Resolution: 16-bit

Channels: 8 simultaneous-sampling

Sampling rate: 200 kSPS per channel

Input ranges: ±10 V and ±5 V true bipolar

Package: 64-LQFP (10mm × 10mm)

Temperature range: –40°C to 85°C

Supply: Single 5 V analog, 2.3V–5.25V logic
