EVAL-AD7606-6EDZ - 16-Bit 200kSPS 6-Ch ADC Eval Board | Analog Devices
MPN： EVAL-AD7606-6EDZ ✓ 啟用中EVAL-AD7606-6EDZ 概覽
A data acquisition system (DAS) is an integrated circuit family that combines the complete analog front-end signal chain and converter on one silicon die, sitting above a plain ADC in the signal-chain hierarchy. Instead of a bare successive-approximation register (SAR) ADC, a DAS integrates analog input clamp protection, an anti-alias filter, track-and-hold amplifiers, a digital filter, a voltage reference, and flexible digital interface logic. This integration removes front-end design effort and reduces component count in multi-channel measurement systems.
The underlying AD7606-6 accommodates true bipolar input signals of ±10 V or ±5 V on all six channels, an unusual capability that removes the need for external level-shifting or front-end conditioning when measuring industrial signals. The on-chip second-order anti-aliasing filter has a 3 dB cutoff frequency of 22 kHz and provides 40 dB anti-alias rejection when sampling at 200 kSPS. An on-chip 2.5 V reference and reference buffer eliminate external reference components. The 16-bit charge-redistribution SAR core with a flexible, pin-driven digital filter improves SNR and can further reduce signal bandwidth.
Typical applications include power-line monitoring and protection systems, multiphase motor control, instrumentation and control systems, multiaxis positioning systems, and general-purpose data acquisition systems. The evaluation board lets engineers exercise simultaneous sampling across channels and evaluate serial or parallel host interfaces quickly.
A key design consideration: the AD7606 family shares one conversion result bus and one sample-and-hold clock across channels, so designers should verify throughput budgeting when migrating between the 8-, 6-, and 4-channel variants. Also note per Analog Devices application note AN-1559 that the AD7606B is a pin-for-pin drop-in upgrade to the base AD7606 with higher input impedance, faster throughput, and extended temperature range.

典型應用
EVAL-AD7606-6EDZ 適用於 6 應用s: Power-Line Monitoring and Protection Systems, Multiphase Motor Control, Instrumentation and Control Systems, Multiaxis Positioning Systems, Data Acquisition Systems (DAS), Grid Infrastructure (DTU / FTU).
Power-Line Monitoring and Protection Systems
Power-line protection relays and monitoring units are the first listed application of the AD7606-6 family. The EVAL-AD7606-6EDZ lets engineers prototype these systems using the 6-channel DAS with ±10 V true bipolar inputs that directly accept voltage transformer (VT) and current transformer (CT) secondary outputs without external front-end scaling. The on-chip analog input clamp protection tolerates fault transients that routinely occur on protection circuits, and simultaneous sampling of all six channels preserves the phase relationships required by symmetrical-component and differential-protection algorithms. The 2nd-order anti-alias filter with 22 kHz, 3 dB cutoff and 40 dB rejection at 200 kSPS removes switching noise ahead of the SAR core, while the 2.5 V on-chip reference and buffer remove external reference error sources from the accuracy budget.

Multiphase Motor Control
Multiphase motor drives and inverters require simultaneous current and voltage feedback on every phase to compute torque, flux, and protection quantities without skew-induced error. The EVAL-AD7606-6EDZ evaluates the AD7606-6, whose six simultaneously sampled 16-bit channels cover three-phase current and voltage sensing in one conversion cycle at up to 200 kSPS. The ±5 V and ±10 V bipolar input ranges match the output of current-sense conditioning stages typical of industrial drives, and the single 5 V supply simplifies isolation design on the control side. Because the device integrates track-and-hold amplifiers with a shared hold command, channel-to-channel sampling skew is eliminated, which is the parameter that most directly affects field-oriented-control accuracy in fast servos and traction inverters.
推薦
Instrumentation and Control Systems
General-purpose industrial instrumentation - multi-sensor monitoring panels, test stands, and process controllers - benefits from the integration level of the AD7606-6 evaluated by this board. A single DAS replaces discrete protection diodes, anti-alias filter stages, sample-and-hold amplifiers, a converter, and a reference, cutting bill-of-materials count and calibration effort. The ±10 V input range accommodates legacy industrial signal standards directly, and the pin-driven flexible digital filter allows a firmware-free trade-off between noise floor and bandwidth during system bring-up. The 16-bit resolution provides roughly 96 dB of theoretical dynamic range, adequate for monitoring both large nominal signals and small anomalies in the same channel, which is common in condition-monitoring instrumentation deployed on rotating machinery and process lines.
推薦
Multiaxis Positioning Systems
Multiaxis positioning and motion platforms - CNC axes, gantries, and optical stages - need synchronized acquisition of position feedback (analog or resolver-derived), force or current feedback, and limit/safety signals. The EVAL-AD7606-6EDZ evaluates the AD7606-6, whose simultaneous sampling guarantees that all axes are observed at the same instant, eliminating the inter-axis time skew that degrades contouring accuracy in coordinated motion. The 200 kSPS per-channel throughput supports servo loop rates far beyond typical 1 kHz to 10 kHz position-loop frequencies, providing headroom for oversampling-based noise reduction through the pin-driven digital filter. True bipolar ±10 V inputs interface directly with analog position sensors and LVDT conditioning electronics common on precision stages.

Data Acquisition Systems (DAS)
Standalone data acquisition systems for test cells, energy meters, and remote monitoring nodes are the archetypal application named in the AD7606-6 datasheet. The EVAL-AD7606-6EDZ provides a complete reference design for such systems: analog input clamp protection, second-order anti-alias filtering, simultaneous track-and-hold, a 16-bit charge-redistribution SAR converter, digital filtering, and a 2.5 V reference on one chip, with serial and parallel host interfaces exposed for FPGA, DSP, or MCU connection. Designers can measure the 40 dB anti-alias rejection at 200 kSPS, validate SNR against system accuracy targets, and reuse the board schematic directly in production hardware. The single 5 V analog supply and wide ±10 V input tolerance reduce external component count versus discrete front-end designs.
推薦
Grid Infrastructure (DTU / FTU)
Distribution and feeder terminal units (DTUs, FTUs) in smart-grid infrastructure are a documented high-volume use case for the AD7606 family; TI forum discussions note that grid products widely deploy AD7606-class converters. The EVAL-AD7606-6EDZ supports prototyping of these units, where six channels cover three-phase voltage and current sensing with fault-record fidelity. The ±10 V direct bipolar inputs match standard secondary transformer levels, the on-chip clamp protection survives switching surges without external suppressors, and 200 kSPS simultaneous sampling enables power-quality and harmonic analysis per measurement standards. The 22 kHz anti-alias filter and flexible digital filter let designers meet both protection-speed and metering-accuracy requirements from a single acquisition path.

設計說明
When migrating a production design from the AD7606-6 to the enhanced AD7606B, do not assume behavioral identity beyond pin compatibility. Per Analog Devices application note AN-1559, the AD7606B is a pin-for-pin replacement with no hardware modifications required, but it differs in hardware-mode register settings, input impedance, throughput, and temperature range. Review the AN-1559 migration table and re-verify digital timing on the bench; one documented TI forum case of a cross-family board swap showed a system slowdown purely due to unverified timing assumptions.
The AD7606-6 samples all six channels simultaneously from a shared track-and-hold, which is its main advantage in phase-sensitive systems such as protection relays and three-phase motor control. Preserve this advantage at board level by keeping analog input routing symmetric and matching trace lengths across channels, and by placing the anti-alias filter network (integrated on chip) close to the input connectors. The integrated 22 kHz, 3 dB filter provides 40 dB rejection at 200 kSPS, so additional external filtering is usually unnecessary unless strong RF interference is present near the sensing lines.
The AD7606-6 operates from a single 5 V analog supply, but the ±10 V bipolar input range means the front-end protection clamps absorb fault energy at the pins. Size the series input resistance and ensure the upstream source can be safely clamped during overvoltage events, per the datasheet input protection section. Because the 2.5 V reference and buffer are on chip, avoid loading the reference externally unless the datasheet permits it; external reference loading is a common cause of gain error in first-time DAS designs.
