Quick Answers: What Is the AD7606BSTZ and Is It Available Now?
The AD7606BSTZ is a 16-bit, 8-channel simultaneous sampling analog-to-digital data acquisition system (DAS) from Analog Devices. It samples all eight channels at 200 kSPS, accepts bipolar ±5V and ±10V inputs, operates from a single 5V supply, and comes in a 64-lead LQFP (10x10 mm) package. The part integrates a second-order antialiasing filter with a 22 kHz cutoff, an internal 2.5V reference, and parallel/serial/SPI/QSPI/MICROWIRE interfaces. As of 2026-08-23, it is active in the XAIPART database with 99,999 units in stock, MOQ 1, and a 1000-piece price of $14.7955.
Simultaneous sampling means V1 through V8 are captured at the same instant, preserving phase relationships between channels. This makes the part well suited for power-line monitoring, protective relays, motor control, multi-axis vibration analysis, data acquisition systems, and instrumentation.
Key verified specifications include 16-bit resolution, eight single-ended input channels, 200 kSPS throughput per channel, bipolar ±5V/±10V input ranges, internal 2.5V reference, SAR architecture, and industrial temperature range -40°C to +85°C.
How to Select, Design In, and Use AD7606BSTZ: Technical Guide
The AD7606BSTZ uses a successive approximation register (SAR) architecture with a charge redistribution DAC. The analog front end includes clamp protection, track-and-hold amplifiers, and a second-order antialiasing filter with a 22 kHz cutoff. This complete signal chain reduces external component count and design risk.
Select the AD7606BSTZ when you need eight simultaneous single-ended channels with 16-bit resolution and 200 kSPS per channel. The input type is single-ended with bipolar ±5V or ±10V ranges. Differential or pseudo-differential signals must be converted to single-ended before reaching V1 through V8.
Package and Power Supply Design
The device is available in a 64-lead LQFP package that measures 10x10 mm and is surface-mount. A single 5V supply powers both AVCC and DVCC; the verified FAQ lists the supply range as 4.75V min to 5.25V max. Place 10 µF and 0.1 µF decoupling capacitors close to the AVCC and DVCC pins, and connect AGND and DGND to a common ground plane.
Reference and Filter Considerations
The internal 2.5V reference and buffer eliminate the need for an external voltage reference. The analog front end includes a second-order antialiasing filter with a 22 kHz cutoff, which simplifies front-end filtering for industrial measurements. For power-line monitoring, this is sufficient to capture harmonics up to the 40th order in 50/60 Hz systems.
Key Pin Functions for a 5V Data Acquisition Front End
| Pin | Name | Function |
|---|---|---|
| 1 | AVCC | Analog supply (5V) |
| 2 | V1 | Analog input channel 1 |
| 9 | V8 | Analog input channel 8 |
| 10 | AGND | Analog ground |
| 11 | REFIN/REFOUT | Reference input/output |
| 12 | REFCAP | Reference buffer output |
| 13 | DVCC | Digital supply (5V) |
| 14 | DGND | Digital ground |
| 15 | CONVST A | Conversion start for channels 1-4 |
| 16 | CONVST B | Conversion start for channels 5-8 |
| 17 | BUSY | Busy output during conversion |
| 18 | CS | Chip select |
| 19 | RD/SCLK | Read/Serial clock |
| 20 | WR/FS | Write/Frame sync |
Typical Design Workflow
- Connect V1-V8 to conditioned single-ended signals within the selected input range. The FAQ notes that the input range is selectable via the RANGE pin for ±5V or ±10V.
- Apply 5V to AVCC and DVCC with recommended decoupling capacitors.
- Drive CONVST A and CONVST B from the same source so all eight channels sample at the same instant.
- Monitor BUSY to detect when conversion is complete.
- Read the 16-bit results through the parallel, serial, SPI, QSPI, or MICROWIRE interface.
Common Application Patterns
The verified application data lists power-line monitoring, protective relays, motor control, multi-axis vibration analysis, general data acquisition systems, and instrumentation. In power-line monitoring, the ±10V range connects directly to standard voltage transformer outputs and preserves phase for accurate power quality analysis. In motor control, all eight channels can monitor three-phase currents and voltages plus additional signals such as DC bus voltage and temperature.
Drop-In Alternatives and Comparison: AD7606BSTZ vs AD7606B vs AD7606C-16BSTZ
The verified XAIPART database lists two direct drop-in alternatives to the AD7606BSTZ. The AD7606B is described as an enhanced version with higher input impedance, faster throughput, and extended temperature range. The AD7606C-16BSTZ is a 16-bit, 8-channel, pin-compatible part with improved performance. In addition, the AD7606BSTZ-RL is the tape-and-reel version of the same device, while the AD7606BSTZ-4 and AD7606BSTZ-6 provide lower channel counts.
