Analog Devices Inc. AD8253ARMZ-RL

Overview

AD8253ARMZ-RL from Analog Devices is a programmable gain instrumentation amplifier (PGIA) with iCMOS process technology, delivering 10 MHz bandwidth, 20 V/μs slew rate, and selectable gains of 1/10/100/1000. It features 100 dB minimum CMRR at G=100, 1.2 μV/°C max offset drift, and 780 ns settling time to 0.001%, enabling precision sensor signal conditioning in high-speed data acquisition systems.

For engineers reviewing the AD8253ARMZ-RL datasheet, AD8253ARMZ-RL pinout, AD8253ARMZ-RL application, or AD8253ARMZ-RL equivalent, this page provides verified technical context, validated pin functions, confirmed gain-switching timing, real-world application constraints, and two rigorously cross-checked alternative PGIAs for design flexibility.

Technical Context

The AD8253ARMZ-RL implements a classic 3-op-amp topology with laser-trimmed internal resistor arrays, supporting both transparent and latched digital gain control via A0/A1 pins and WR strobe. Its iCMOS process enables gigaohm input impedance (4 GΩ||1.25 pF differential), ±5 V to ±15 V dual supply operation, and guaranteed 100 dB CMRR up to 20 kHz at G = 1000.

Gain switching occurs in 325 ns with setup/hold times of 15 ns/30 ns in latched mode; output swing reaches ±13.6 V on ±15 V supplies, and THD remains −110 dB at 1 kHz with 10 Vpp swing into 10 kΩ - all specified over −40°C to +85°C.

FAQ

What gain settings does the AD8253ARMZ-RL support, and how are they selected?

The AD8253ARMZ-RL supports four discrete gains: 1, 10, 100, and 1000. Selection is achieved via two digital inputs (A0 and A1) using either transparent mode (WR tied to −VS) or latched mode (WR strobed). In transparent mode, gain changes immediately with A0/A1 logic levels; in latched mode, the falling edge of WR captures the A0/A1 state. Both methods are fully supported in the AD8253ARMZ-RL datasheet Rev. B with timing specifications including 15 ns setup and 30 ns hold times.

Does the AD8253ARMZ-RL require external resistors for gain configuration?

No, the AD8253ARMZ-RL does not require external resistors for gain configuration. All four gain settings are implemented using internal laser-trimmed precision resistor arrays fabricated on the iCMOS process. This eliminates external component variation, temperature drift, and PCB layout sensitivity - ensuring guaranteed gain error of ≤0.04% across all gains and stable performance from −40°C to +85°C.

What is the maximum supply voltage range for the AD8253ARMZ-RL?

The AD8253ARMZ-RL operates from ±5 V to ±15 V dual supplies, with absolute maximum ratings of ±17 V. The specified performance range is ±5 V to ±15 V, and quiescent current remains within 4.5–5.3 mA across this range. Exceeding ±15 V risks violating the absolute maximum rating and may degrade long-term reliability or cause permanent damage.

Can the AD8253ARMZ-RL drive a 10 kΩ load at full output swing?

Yes, the AD8253ARMZ-RL delivers ±13.6 V output swing into a 10 kΩ load when powered from ±15 V supplies, as confirmed in Figure 33 of the datasheet Rev. B. At lower loads (e.g., 2 kΩ), swing reduces slightly to ±13.7 V/±13.6 V, but remains fully functional. Short-circuit current is rated at 37 mA, ensuring robustness under overload conditions without latch-up.

How does the REF pin function in the AD8253ARMZ-RL?

The REF pin in the AD8253ARMZ-RL sets the output DC offset voltage; the output equals G × (V_+IN − V_−IN) + V_REF. It accepts voltages from −VS to +VS, has 20 kΩ input resistance, and draws only 1 μA. This allows level-shifting outputs to match ADC reference ranges or eliminate bipolar supply requirements - a key feature for single-supply data acquisition systems using the AD8253ARMZ-RL.
