Analog Devices Inc. OP262HRUZ

Overview

OP262HRUZ from Analog Devices is a dual-channel, rail-to-rail output operational amplifier optimized for precision, low-power, high-speed signal conditioning in single-supply systems. It delivers 15 MHz gain-bandwidth, 13 V/µs slew rate, 325 µV max input offset voltage, and operates from 2.7 V to 12 V (±1.35 V to ±6 V). It is used in portable instrumentation front-ends and sampling ADC driver stages where dynamic range and low quiescent current (500 µA per amplifier) are critical.

For engineers reviewing the OP262HRUZ datasheet, OP262HRUZ pinout, OP262HRUZ application, or OP262HRUZ equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional and packaging differences - all specific to the OP262HRUZ (8-lead TSSOP, RU suffix, H-grade temperature rating).

Technical Context

The OP262HRUZ uses Analog Devices' XFCB high-speed complementary bipolar process with trench isolation, enabling both 15 MHz bandwidth and sub-mV offset accuracy. Its PNP input stage with cross-coupled emitters achieves low noise (9.5 nV/√Hz @ 1 kHz) and high slew rate without emitter degeneration resistors.

Rail-to-rail output swing is achieved via complementary common-emitter output transistors, delivering ≤50 mV from rails at <1 mA load and ≤150 mV at 5 mA. The device is unity-gain stable, exhibits no phase reversal up to ±6 V input overvoltage, and supports extended industrial operation from –40°C to +125°C.

FAQ

What is the maximum operating temperature range for the OP262HRUZ?

The OP262HRUZ is rated for operation from –40°C to +125°C, meeting the extended industrial temperature specification (H grade). This is confirmed in Table 1, Table 2, and Table 3 of the Rev. H datasheet, and applies to all electrical parameters including offset voltage, CMRR, and output swing. The device's thermal resistance (θ_JA = 208°C/W) must be considered in PCB layout to maintain junction temperature below 150°C under worst-case load conditions. OP262HRUZ maintains full functionality across this entire range without derating.

Does the OP262HRUZ support true rail-to-rail input operation?

No, the OP262HRUZ does not support rail-to-rail input. Its common-mode input voltage range is specified as 0 V to (V+) – 1 V in single-supply mode, and –5 V to +4 V in ±5 V dual-supply mode. This means the input cannot swing to the positive rail - it stops 1 V short. However, the output is fully rail-to-rail, achieving ≤150 mV from either supply rail at 5 mA load. This asymmetric input/output behavior is explicitly detailed in the "Rail-to-Rail Output" section (Page 12) and Table 1–3 input voltage range entries.

Can the OP262HRUZ drive a 100 pF capacitive load stably?

Yes, the OP262HRUZ can drive up to 100 pF capacitive load while maintaining stability and ≤10% overshoot, as confirmed in Figure 20 ("Small-Signal Overshoot vs. Capacitance") and the "Capacitive Load Drive" section (Page 14). At 100 pF, overshoot remains below 5%, and settling time increases only modestly. For loads >100 pF, external compensation (e.g., series R-C isolation) is recommended per Figure 38 guidance. This capability enables direct connection to ADC input capacitors and long PCB traces without added buffer stages.

What is the purpose of Pin 1 and Pin 8 on the OP262HRUZ?

Pin 1 (–IN A) and Pin 8 (V+) are standard functional pins: Pin 1 is the inverting input of Amplifier A; Pin 8 is the positive supply terminal. Neither serves as an offset null pin. Offset adjustment is supported only on the single-channel OP162 (via Pins 1 and 8), not on the dual OP262HRUZ - a distinction clearly stated in the "Offset Adjustment" section (Page 12), which specifies "Figure 31 shows how the OP162 offset voltage can be adjusted". OP262HRUZ has no internal nulling connections; its 1 mV max offset is trimmed at wafer test.

Is the OP262HRUZ protected against output short-circuit conditions?

No, the OP262HRUZ is not short-circuit protected. As stated in the "Output Short-Circuit Protection" section (Page 12), "the output of the OP162/OP262/OP462 are not short-circuit protected. Shorting the output directly to ground or to a supply rail may destroy the device." The absolute maximum rating for short-circuit current is ±80 mA, but safe continuous output current is limited to ±30 mA. External series current-limiting resistors (e.g., 169 Ω for 5 V supply) are required in applications where accidental shorts are possible - per Figure 32 implementation guidance.
