Product details
Overview
AD4005BCPZ-RL7 from Analog Devices is a 16-bit, 1 MSPS precision differential SAR ADC with Easy Drive architecture, ±VREF input range (2.4 V–5.1 V), −40°C to +125°C operation, and 3 mm × 3 mm LFCSP package. It delivers 96.2 dB SNR at 1 kHz and ±0.4 LSB INL for high-fidelity data acquisition in battery-powered instrumentation.
For engineers reviewing the AD4005BCPZ-RL7 datasheet, AD4005BCPZ-RL7 pinout, AD4005BCPZ-RL7 application, or AD4005BCPZ-RL7 equivalent, key selection criteria include guaranteed 16-bit no-missing-codes performance, low 4.9 mW VDD-only power at 1 MSPS, input overvoltage clamp (±50 mA), SPI/QSPI/MICROWIRE compatibility, and high-Z mode enabling direct drive from low-power amplifiers without external buffers.
Technical Context
The AD4005BCPZ-RL7 implements a successive approximation register (SAR) architecture with integrated Easy Drive circuitry that reduces input current to ≤1 μA at 1 MSPS and extends acquisition time to ≥79% of the conversion cycle. Its differential analog front-end supports ±VREF input span compression and features an input overvoltage clamp protecting against ±50 mA transients while minimizing reference pin disturbance.
Digital interface flexibility includes CS-mode (3-/4-wire) and daisy-chain modes, all compatible with 1.8 V–5.5 V VIO logic. Conversion results are available immediately post-conversion with zero pipeline latency, and status bits support real-time monitoring of acquisition state and error conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with guaranteed no missing codes - ensures full dynamic range utilization without code gaps in precision measurement. |
| Throughput Rate | 1 MSPS - enables accurate capture of signals up to ~400 kHz (Nyquist-limited) in single-shot or continuous mode. |
| INL / DNL | ±0.4 LSB / ±0.5 LSB - maintains linearity critical for calibration-sensitive applications like medical sensor interfaces. |
| SNR @ 1 kHz | 96.2 dB at VREF = 5 V - delivers >15.7 effective number of bits (ENOB) for high-fidelity signal digitization. |
| Power (VDD only) | 4.9 mW at 1 MSPS - enables ultra-low-power operation from 1.8 V supply, ideal for portable and energy-constrained systems. |
| Input Voltage Range | ±VREF (2.4 V–5.1 V) - supports flexible reference scaling while preserving full 16-bit code range via span compression. |
| Operating Temperature | −40°C to +125°C - qualified for industrial and automotive under-hood environments without derating. |
Pinout & Package
AD4005BCPZ-RL7 is housed in a 10-lead, 3 mm × 3 mm LFCSP (CP-10-9) package with exposed pad connected to GND. Thermal resistance θJC = 33°C/W supports reliable operation at full throughput in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF | Analog reference input | Accepts 2.4 V–5.1 V external reference; requires local 10 µF X7R decoupling to GND for noise immunity. |
| VDD | Analog power supply | 1.71 V–1.89 V single supply; bypassed with 0.1 µF ceramic capacitor to GND for stable core operation. |
| IN+, IN− | Differential analog inputs | High-Z mode reduces input current to ≤1 µA; supports ±VREF range and overvoltage clamp up to ±50 mA. |
| GND | Power ground | Common return for VDD, REF, and digital supplies; must connect to low-impedance PCB ground plane. |
| CNV | Convert control input | Rising edge initiates conversion and selects interface mode (CS vs. daisy-chain); also enables SDO in CS mode when low. |
| SDO | Serial data output | Outputs 16-bit two's complement result synchronized to SCK; tri-states when CNV is high in CS mode. |
| SCK | Serial clock input | Drives data shift-out; supports up to 100 MHz in turbo mode for 1 MSPS operation with minimal digital power. |
| SDI | Serial data input | Configures interface mode on CNV rising edge (high = CS, low = daisy-chain); accepts command writes in register mode. |
| VIO | I/O logic supply | 1.71 V–5.5 V independent supply enabling interoperability with 1.8 V/2.5 V/3.3 V/5 V digital hosts. |
Key Features
| Feature | Design Value |
|---|---|
| Easy Drive input architecture | Reduces input current to ≤1 µA at 1 MSPS and extends acquisition phase to 790 ns - eliminates need for high-speed ADC driver amplifiers. |
| Input overvoltage clamp | Sinks up to ±50 mA at IN+/IN− while limiting voltage excursion to ≤5.4 V (VREF = 5 V) - protects ADC and reference without external diodes. |
| Span compression | Shifts input range to 0.1×VREF to 0.9×VREF - enables single-supply operation without negative rail while retaining full 16-bit code utilization. |
| Zero-latency conversion | First conversion is accurate with no pipeline delay - supports deterministic timing in closed-loop control and real-time triggering applications. |
| Oversampled dynamic range | 126 dB at OSR = 1024 - enhances resolution for low-frequency DC/low-bandwidth measurements without hardware filter redesign. |

FAQ
What is the maximum sampling rate supported by the AD4005BCPZ-RL7?
The AD4005BCPZ-RL7 supports a maximum throughput rate of 1 MSPS under specified conditions (turbo mode enabled, VIO ≥ 2.7 V, SCK ≥ 80 MHz). This is fixed per its variant designation-unlike the AD4001BCPZ-RL7, which supports 2 MSPS. The 1 MSPS rate ensures full AC/DC specifications including ±0.4 LSB INL and 96.2 dB SNR are maintained across the full operating temperature range.
Does the AD4005BCPZ-RL7 require an external ADC driver amplifier?
No-the AD4005BCPZ-RL7's Easy Drive architecture reduces input current to ≤1 µA at 1 MSPS and provides a 790 ns acquisition window, enabling direct connection to low-output-impedance sources such as precision op amps, instrumentation amplifiers, or resistive sensor bridges without buffer stages. This eliminates driver-related noise, power, and layout complexity typically associated with high-resolution SAR ADCs.
Can the AD4005BCPZ-RL7 operate with a 2.5 V reference voltage?
Yes-the AD4005BCPZ-RL7 supports VREF from 2.4 V to 5.1 V. At VREF = 2.5 V, it delivers 92.1 dB SNR and maintains full 16-bit no-missing-codes performance. Input span compression remains functional, shifting the usable analog input range to 0.25 V–2.25 V (0.1× to 0.9×VREF), preserving dynamic range while simplifying single-supply signal conditioning.
How does the input overvoltage clamp function on the AD4005BCPZ-RL7?
The AD4005BCPZ-RL7 integrates internal clamps on IN+ and IN− that activate when input voltage exceeds VREF-based thresholds (e.g., 5.25 V for VREF = 5 V). Each clamp safely sinks up to ±50 mA for short durations, limiting voltage excursion to ≤5.4 V and preventing damage to the ADC core or reference. Clamp deactivation occurs within 360 ns, minimizing disruption to subsequent conversions.
Is the AD4005BCPZ-RL7 pin-compatible with other devices in the AD400x family?
Yes-the AD4005BCPZ-RL7 shares identical 10-lead LFCSP (3 mm × 3 mm) and MSOP (3 mm × 4.9 mm) footprints with AD4001/AD4003/AD4007/AD4011. Pin functions, electrical characteristics, and interface protocols are fully aligned, enabling drop-in replacement within the same package variant for throughput or feature trade-offs-e.g., upgrading to AD4003BCPZ-RL7 for 2 MSPS without layout changes.
