Product details
Overview
AD7262BCPZ from Analog Devices is a dual-channel, 12-bit, simultaneous-sampling SAR ADC with integrated programmable gain amplifier (PGA), on-chip 2.5 V reference, and four independent comparators. It delivers 1 MSPS throughput per channel, supports true differential analog inputs with >1 GΩ input impedance, and operates across −40°C to +105°C for motor control position feedback and sensor monitoring applications.
For engineers reviewing the AD7262BCPZ datasheet, AD7262BCPZ pinout, AD7262BCPZ application, or AD7262BCPZ equivalent, this page provides verified technical context, calibrated performance data, validated package mapping, and real-world design implications for high-precision dual-channel acquisition systems.
Technical Context
The AD7262BCPZ implements two independent successive approximation register (SAR) ADCs with synchronized sampling clocks and separate serial output lines (DOUTA/DOUTB), enabling true simultaneous conversion of two channels without inter-channel skew. Each ADC path includes a front-end PGA with 14 selectable gains (×1 to ×128) and a dedicated 2.5 V reference buffer.
Four on-chip comparators are partitioned into two low-power pairs (A/B) and two fast-propagation pairs (C/D), each with independent supply domains (CA_CBVCC/CC_CDVCC) and ground references (CA_CB_GND/CC_CD_GND), supporting autonomous signal edge detection in encoder interfaces and overcurrent monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - guarantees monotonicity and no missing codes across full operating temperature range. |
| Throughput Rate | 1 MSPS per ADC - enables real-time capture of fast-changing motor position or vibration signals. |
| PGA Gain Range | ×1 to ×128 in 14 discrete steps - allows direct digitization of mV-level sensor outputs without external amplification. |
| SNR | 73 dB typical at gain = 2 - supports >11 effective bits for precision current sensing at 100 kHz input tone. |
| Input Impedance | >1 GΩ - minimizes loading on high-impedance piezoelectric or capacitive sensors. |
| Reference | On-chip 2.5 V ±5 mV - eliminates need for external reference IC while maintaining <20 ppm/°C drift. |
| Comparator Propagation Delay | 0.12 µs (C/D) / 0.93 µs (A/B) - enables sub-microsecond response for commutation timing in BLDC drives. |
Pinout & Package
The AD7262BCPZ is housed in a 48-lead LFCSP (Lead Frame Chip Scale Package) with exposed metal paddle requiring soldering to PCB ground for thermal management and noise reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VA+, VA− | Analog Input A | True differential input pair for first ADC channel; accepts ±VREF/2 centered at common-mode voltage. |
| VB+, VB− | Analog Input B | True differential input pair for second ADC channel; fully independent and simultaneously sampled with Channel A. |
| DOUTA, DOUTB | Serial Data Outputs | Separate MSB-first twos-complement streams for each ADC; support simultaneous readout or daisy-chained single-port access. |
| G0–G3 | PGA Gain Select | Hardwired logic inputs setting one of 14 gain values; alternative programming via control register when PD0/DIN enabled. |
| COUTA–COUTD | Comparator Outputs | CMOS push-pull digital outputs referenced to VDRIVE; C/D optimized for speed, A/B for ultra-low quiescent current. |
| VREFA, VREFB | Reference I/O | Buffered 2.5 V reference outputs; can source/sink up to 1 mA and serve as system-wide reference if REFSEL = high. |
| REFSEL | Reference Selection | Logic input selecting internal 2.5 V reference (high) or external reference applied to VREFA/VREFB (low). |
| PD0/DIN, PD1, PD2 | Power-Down Control | Three-pin encoding selects shutdown mode (full, ADC-only, comparator-only); PD0 doubles as serial data input when all G pins are low. |
Key Features
| Feature | Design Value |
|---|---|
| Dual simultaneous sampling | Eliminates phase mismatch between channels-critical for vector control algorithms requiring synchronized current and back-EMF measurements. |
| Integrated PGA with 14 gain settings | Enables single-chip scaling of diverse sensor outputs (e.g., shunt resistors, RTDs, LVDTs) without external op-amps or gain-switching circuitry. |
| Four independent comparators | Supports concurrent monitoring of multiple encoder poles or fault conditions-A/B for standby power savings, C/D for time-critical event triggering. |
| On-chip offset and gain calibration | Removes device-specific errors and compensates for sensor offset/gain drift-reduces factory calibration burden and improves long-term accuracy. |
| Flexible reference architecture | Internal 2.5 V reference usable standalone or buffered externally; REFSEL pin allows seamless transition to higher-accuracy external references. |
Applications
| Motor Control Position Feedback | Sensor Signal Conditioning |

Use Value: Independent comparator supplies (CA_CBVCC/CC_CDVCC) allow selective power gating-reducing total system current by >90% during standstill. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7264BCPZ | 12-bit, 1 MSPS dual ADC with same PGA and comparator architecture but adds 12-bit DACs per channel. | Required when closed-loop control demands integrated DAC feedback (e.g., adaptive biasing, waveform synthesis). | Select AD7264BCPZ only if DAC functionality is needed-adds cost and complexity without benefit for pure acquisition roles. |
| ADS8588HIPM | 16-bit, 1 MSPS simultaneous-sampling ADC with ±10 V input range, no integrated PGA or comparators. | Suitable for high-dynamic-range applications (e.g., power quality analyzers) where external signal conditioning is already present. | Choose ADS8588HIPM when resolution >12-bit and wide input range are mandatory-sacrifices on-chip gain flexibility and comparator integration. |
Compared with AD7262BCPZ, AD7264BCPZ adds DACs at the cost of higher power and price, while ADS8588HIPM trades integrated signal conditioning for raw resolution-making AD7262BCPZ optimal for compact, self-contained motor control and sensor acquisition where PGA gain and comparator autonomy are essential.

FAQ
What is the maximum sampling rate supported by the AD7262BCPZ?
The AD7262BCPZ supports a maximum throughput rate of 1 MSPS per ADC channel under specified conditions (AVCC = 5.25 V, fSCLK = 40 MHz). This rate applies to both channels simultaneously, with conversion time fixed at 19 × tSCLK. The AD7262BCPZ achieves this performance while maintaining 73 dB SNR at PGA gain = 2 and full 12-bit linearity across −40°C to +105°C.
Does the AD7262BCPZ require an external reference voltage?
No, the AD7262BCPZ includes an on-chip 2.5 V reference with ±5 mV accuracy at 25°C and 20 ppm/°C temperature coefficient, accessible via VREFA and VREFB pins. An external reference may be used by pulling REFSEL low and applying a stable voltage to VREFA/VREFB-enabling higher-accuracy or customized reference schemes without modifying the AD7262BCPZ's core functionality.
How many gain settings does the PGA in the AD7262BCPZ support?
The AD7262BCPZ integrates a programmable gain amplifier with 14 discrete gain settings: ×1, ×2, ×3, ×4, ×6, ×8, ×12, ×16, ×24, ×32, ×48, ×64, ×96, and ×128. These are selected either via hardwired G0–G3 pins or through the control register when PD0/DIN mode is enabled-providing flexible signal scaling for diverse sensor types without external components.
Can the AD7262BCPZ perform simultaneous sampling on both channels?
Yes, the AD7262BCPZ features true simultaneous sampling architecture: both ADCs share a common sampling clock and acquire their respective analog inputs (VA± and VB±) at the exact same instant. This eliminates inter-channel phase error-critical for vector control, power measurement, and differential signal analysis where timing coherence between channels is mandatory.
What are the key differences between the comparators in the AD7262BCPZ?
The AD7262BCPZ contains four comparators split into two functional groups: Comparators A and B are optimized for ultra-low quiescent current (3 µA at 3.3 V), ideal for standby monitoring; Comparators C and D prioritize speed with 0.12 µs propagation delay at 5 V, suited for real-time commutation or fault detection. Each group has independent supply (CA_CBVCC/CC_CDVCC) and ground (CA_CB_GND/CC_CD_GND) domains.
