Analog Devices Inc. AD9214BRSZ-RL105

Overview

AD9214BRSZ-RL105 from Analog Devices is a 10-bit, 105 MSPS monolithic analog-to-digital converter with on-chip track-and-hold, single 3.3 V supply operation, 300 MHz analog bandwidth, and selectable 1 V_p-p/2 V_p-p input range - used in ultrasound front-ends and broadband wireless receivers.

For engineers reviewing the AD9214BRSZ-RL105 datasheet, AD9214BRSZ-RL105 pinout, AD9214BRSZ-RL105 application, or AD9214BRSZ-RL105 equivalent, key selection criteria include SNR at 39 MHz (57 dB), power consumption at 105 MSPS (285 mW), pipeline latency (5 clock cycles), ENOB at 10 MHz (9.3 bits), and differential nonlinearity (±0.08 LSB).

Technical Context

The AD9214BRSZ-RL105 implements a bit-per-stage pipeline architecture with switch-capacitor techniques to deliver 10-bit resolution at up to 105 MSPS, featuring integrated track/hold, internal 1.25 V reference (configurable via REFSENSE), and dual-supply operation (AVDD for analog core, DrVDD for digital outputs). It supports both twos complement and offset binary output formats.

Its analog input stage is fully differential with internal biasing at AVDD/3, enabling ac- or dc-coupled operation; the DFS/GAIN pin selects either 1 V_p-p or 2 V_p-p full-scale range and corresponding data format, while the OR pin provides real-time out-of-range detection synchronized to the output data stream.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog input frequency supported by the AD9214BRSZ-RL105?

The AD9214BRSZ-RL105 features a 300 MHz analog input bandwidth, meaning it can accurately digitize signals with fundamental frequencies up to 300 MHz before significant amplitude attenuation occurs. However, its usable Nyquist-limited input frequency is 52.5 MHz at 105 MSPS sampling. The 300 MHz specification reflects the −3 dB point of the analog input buffer, not the sampling theorem limit.

Does the AD9214BRSZ-RL105 require an external reference voltage?

No, the AD9214BRSZ-RL105 includes an internal 1.25 V reference that is enabled by default when REFSENSE (Pin 3) is tied to AGND. REF (Pin 4) then functions as a reference output. An external reference is optional and only needed when higher precision or temperature stability is required beyond the internal reference's ±80 ppm/°C drift.

How does the DFS/GAIN pin affect the AD9214BRSZ-RL105's operation?

The DFS/GAIN pin (Pin 2) simultaneously configures both the output data format (twos complement or offset binary) and the full-scale analog input range (1 V_p-p or 2 V_p-p). Its state - connected to AVDD, AGND, REF, or left floating - determines this dual behavior per Table 8 in the datasheet. This eliminates need for separate control lines and simplifies configuration.

What is the power-down current consumption of the AD9214BRSZ-RL105?

In power-down mode (PWRDN = HIGH), the AD9214BRSZ-RL105 draws 10–15 mA from AVDD at 3.0 V, resulting in 30 mW total power consumption. All analog circuitry is disabled, and digital outputs enter high-impedance state. Recovery to full operation requires approximately 15 clock cycles before valid data appears on D0–D9.

Can the AD9214BRSZ-RL105 interface directly with 2.5 V logic families?

Yes, the AD9214BRSZ-RL105 supports direct 2.5 V logic interfacing via its dedicated DrVDD supply pins (Pins 16 and 24). When DrVDD is set to 2.5 V, the D0–D9 outputs swing between 0 V and 2.5 V with TTL/CMOS-compatible thresholds, eliminating need for external level translators in mixed-voltage systems.
