Overview
AD9216BCPZRL7-65 from Analog Devices is a dual, 10-bit, 65 MSPS analog-to-digital converter (ADC) fabricated in advanced CMOS, featuring differential sample-and-hold amplifiers, integrated voltage reference, and clock duty cycle stabilizer. It delivers 56.6 dBc SNR at Nyquist, −80 dB crosstalk, and operates from a single 3 V supply with 234 mW total power consumption. Used in IF sampling for communications receivers and handheld scopemeters.
For engineers reviewing the AD9216BCPZRL7-65 datasheet, AD9216BCPZRL7-65 pinout, AD9216BCPZRL7-65 application, or AD9216BCPZRL7-65 equivalent, key selection criteria include dual-channel interleaving capability, 300 MHz analog input bandwidth, guaranteed no missing codes over −40°C to +85°C, and support for offset binary or twos complement output formats.
Technical Context
The AD9216BCPZRL7-65 employs a multistage differential pipelined architecture with output error correction logic to ensure 10-bit accuracy and no missing codes across temperature. Its dual SHA inputs support both differential and single-ended configurations with 2.0 Vp-p full-scale range and 2 pF input capacitance.
It features independent channel control via PWDN_A/PWDN_B and OEB_A/OEB_B, shared or independent reference mode selectable via SHARED_REF, and data format selection (offset binary/twos complement) via DFS. The DCS circuit maintains performance across wide clock duty cycle variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - guarantees monotonic transfer function and no missing codes over full industrial temperature range. |
| Max Sample Rate | 65 MSPS - supports undersampling of IF signals up to ~32 MHz Nyquist frequency with adequate timing margin. |
| SNR @ Nyquist | 56.6 dBc - enables >9-bit effective resolution for baseband or IF digitization in receiver front-ends. |
| Crosstalk | < −80 dB - ensures minimal inter-channel interference in time-interleaved or simultaneous dual-signal acquisition. |
| Analog Bandwidth | 300 MHz - allows clean digitization of wideband signals including harmonics up to third order without attenuation. |
| Power Consumption | 234 mW at 65 MSPS - balances performance and thermal load in space-constrained portable instrumentation. |
| Supply Voltages | AVDD = 3.0 V ±0.3 V, DRVDD = 2.5 V ±0.25 V - requires separate analog/digital rail decoupling per layout guidelines. |
| Aperture Jitter | 0.5 ps rms - limits SNR degradation at high input frequencies; critical for >50 MHz signal fidelity. |
Pinout & Package
The AD9216BCPZRL7-65 is housed in a Pb-free, 64-lead LFCSP package (9 mm × 9 mm), thermally enhanced with exposed paddle, rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+_A / VIN−_A VIN+_B / VIN−_B | Differential analog inputs (Ch A & Ch B) | Accept 2.0 Vp-p differential signals; support single-ended use with external bias; 300 MHz bandwidth enables RF/IF sampling. |
| CLK_A / CLK_B | Independent encode clocks per channel | Enable asynchronous or synchronized dual-channel sampling; duty cycle stabilizer (DCS) mitigates jitter from non-50% clocks. |
| OEB_A / OEB_B | Output enable controls (active low) | Place respective 10-bit data buses (D0–D9) into high-impedance state - essential for multiplexed bus sharing or power gating. |
| PWDN_A / PWDN_B | Channel power-down (active high) | Reduces channel power to standby level (3.0 mW) while preserving configuration; outputs remain static, not tri-stated. |
| DFS | Data format select | Low = offset binary; high = twos complement - determines digital interface compatibility with FPGA/DSP logic. |
| SHARED_REF | Reference mode control | High = shared internal reference between channels (improves gain matching to ±0.1% FSR); low = independent references. |
| DCS | Duty cycle stabilizer enable | Active-high control for internal clock conditioning circuit - required to maintain AC specs with asymmetric clocks. |
| AVDD / AGND / DRVDD / DRGND | Separate analog/digital supplies & grounds | Mandatory isolation prevents digital switching noise from degrading analog performance; AVDD/AGND must be star-connected. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 10-bit pipelined ADCs with error correction | Guarantees no missing codes and 10-bit linearity (±1.4 LSB INL max) across −40°C to +85°C without calibration. |
| Integrated voltage reference and SENSE pin | Eliminates need for external reference; SENSE selects internal 1.0 V reference or external reference mode with 15 ppm/°C drift spec. |
| Patented differential SHA with 300 MHz BW | Enables direct sampling of IF signals up to 200 MHz while maintaining >56 dB SNR - avoids external anti-alias filtering complexity. |
| Channel crosstalk < −80 dB | Permits simultaneous digitization of two independent RF paths (e.g., I/Q or diversity antennas) without measurable coupling. |
| 64-lead LFCSP with exposed thermal paddle | θJA = 26.4°C/W enables stable operation at full speed in compact PCB layouts without forced air or heatsinks. |
| Single 3 V analog supply with 2.5 V digital driver | Simplifies power design versus mixed-voltage ADCs; AVDD and DRVDD can share regulator if PSRR (±0.1% FSR) is verified in system. |

FAQ
What is the maximum analog input frequency supported by the AD9216BCPZRL7-65?
The AD9216BCPZRL7-65 has a specified analog bandwidth of 300 MHz, meaning it maintains flat frequency response (−3 dB point) up to that frequency. It reliably digitizes signals up to 200 MHz while preserving >56 dBc SNR, as validated in typical performance curves. Input signals beyond 200 MHz may exhibit increased harmonic distortion but remain within datasheet AC specifications up to the 300 MHz bandwidth limit.
Does the AD9216BCPZRL7-65 require an external voltage reference?
No, the AD9216BCPZRL7-65 includes an integrated 1.0 V reference with ±2 mV output voltage error and ±15 ppm/°C drift. The SENSE pin allows selection between internal reference mode (default) or external reference mode. When using the internal reference, REFT_A/REFB_A and REFT_B/REFB_B pins are connected as differential reference inputs per channel, and VREF serves as reference output.
How does the clock duty cycle stabilizer (DCS) function in the AD9216BCPZRL7-65?
The DCS circuit in the AD9216BCPZRL7-65 actively conditions incoming CLK_A and CLK_B signals to produce internally generated clocks with near-50% duty cycle, regardless of input duty cycle variation. Enabled via the DCS pin (active high), it ensures consistent aperture timing and maintains SNR/SFDR performance even with highly asymmetric clocks (e.g., 30/70 duty cycle), eliminating need for external clock cleanup circuits.
Can both channels of the AD9216BCPZRL7-65 operate independently?
Yes, the AD9216BCPZRL7-65 supports fully independent channel operation: CLK_A and CLK_B accept separate clocks; PWDN_A/PWDN_B and OEB_A/OEB_B provide per-channel power-down and output enable control; and SHARED_REF configures reference mode (shared or independent). This enables asynchronous sampling, staggered acquisition, or single-channel low-power modes without affecting the other channel's configuration.
What is the purpose of the MUX_SELECT pin on the AD9216BCPZRL7-65?
The MUX_SELECT pin configures the AD9216BCPZRL7-65 for multiplexed output mode, where both Channel A and Channel B 10-bit data are time-division multiplexed onto a single 10-bit bus (D0–D9) with frame synchronization indicated by OEB_A/OEB_B toggling. This reduces FPGA pin count and routing complexity in systems where simultaneous dual-channel throughput is not required, trading bandwidth for interface simplicity.
