Product details
Overview
LT6023IDD-1#PBF from Analog Devices (formerly Linear Technology) is a dual micropower precision rail-to-rail output operational amplifier with integrated shutdown control. It delivers 1.4 V/µs slew rate, 40 kHz gain-bandwidth product, ≤30 µV input offset voltage, 20 µA/amplifier supply current, and operates from 3 V to 30 V supplies. It is optimized for multiplexed ADC buffering in low-power portable instrumentation.
For engineers reviewing the LT6023IDD-1#PBF datasheet, LT6023IDD-1#PBF pinout, LT6023IDD-1#PBF application, or LT6023IDD-1#PBF equivalent, this page provides verified package mapping (10-lead DFN), confirmed shutdown functionality (EN/DGND pins), validated rail-to-rail output swing (≤190 mV from rails), exact input bias current (±1 nA), and real-world settling performance (132 µs to 0.0015% for 10 V step).
Technical Context
The LT6023IDD-1#PBF implements a proprietary dual-input-stage topology combining NPN and PNP differential pairs to maintain high dynamic input impedance during ±5 V input transients-critical for MUX channel switching. Its enhanced slew rate scales with input step size (0.65 V/µs for 5 V, 1.4 V/µs for 10 V), unlike conventional micropower op-amps.
Shutdown is controlled via EN and DGND pins: EN must exceed DGND + 1.7 V to enable; below DGND + 0.8 V, supply current drops to ≤3.2 µA. Output remains high-impedance in shutdown, and wake-up time is 480 µs-enabling duty-cycled operation in wireless sensor nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2050HMS8#PBF | Zero-drift architecture; 0.5 µV max offset, but 1.1 MHz GBW and 170 µA supply current; no shutdown | Better DC accuracy for ultra-low-drift systems; unsuitable for micropower or shutdown-reliant designs | Select only if sub-µV offset and drift dominate over power and control requirements |
| OPA2333AIDRGT | Zero-drift, 17 µA supply current, 350 kHz GBW, rail-to-rail I/O, no shutdown; 8-pin WSON package | Higher speed and lower offset than LT6023IDD-1#PBF, but lacks EN/DGND control and 10-lead DFN thermal profile | Prefer when zero-drift stability is critical and shutdown is managed externally |
Compared with LTC2050HMS8#PBF and OPA2333AIDRGT, the LT6023IDD-1#PBF uniquely balances micropower operation (20 µA), usable slew rate (1.4 V/µs), integrated shutdown (≤3.2 µA), and 10-lead DFN thermal performance-making it the only option for space-constrained, battery-powered MUX-buffering where wake-up latency and thermal dissipation are design constraints.

FAQ
What is the maximum supply voltage for the LT6023IDD-1#PBF?
The LT6023IDD-1#PBF has an absolute maximum total supply voltage (V+ to V–) rating of 36 V. Operation is specified from 3 V to 30 V. Exceeding 36 V risks permanent damage, per Absolute Maximum Ratings on page 2 of the official datasheet.
Does the LT6023IDD-1#PBF support rail-to-rail input operation?
No-the LT6023IDD-1#PBF features rail-to-rail *output* but not rail-to-rail *input*. Its common-mode input range is limited to V– + 1.2 V to V+ – 1.4 V. However, Figure 2 in the datasheet shows how inverting and noninverting gain configurations can achieve full-rail system performance without requiring rail-to-rail inputs.
How does the EN pin function on the LT6023IDD-1#PBF?
The EN pin on the LT6023IDD-1#PBF is an active-high enable control referenced to the DGND pin. To activate the device, EN must be ≥ DGND + 1.7 V; to enter shutdown, EN must be ≤ DGND + 0.8 V. The LT6023IDD-1#PBF outputs go high-impedance in shutdown, and wake-up occurs within 480 µs.
What is the typical input bias current of the LT6023IDD-1#PBF?
The LT6023IDD-1#PBF has a maximum input bias current of ±1 nA over temperature (–40°C to 85°C), with typical values near ±0.1 nA at 25°C. This ultra-low bias current minimizes voltage errors in high-impedance sensor interfaces and reference dividers.
Can the LT6023IDD-1#PBF drive capacitive loads?
Yes-the LT6023IDD-1#PBF can drive up to 100 pF in unity-gain configuration. Driving larger capacitive loads (e.g., ADC input capacitance + PCB trace) is supported by adding a small series resistor (e.g., 10–50 Ω) between the output and load, which improves phase margin without degrading DC accuracy.
