Product details
Overview
TLV2170IDR from Texas Instruments is a dual-channel, 36-V, rail-to-rail output operational amplifier with EMI-hardened inputs, 1.2 MHz gain bandwidth, 22 nV/√Hz input voltage noise, and 125 µA quiescent current per amplifier-designed for precision signal conditioning in server power supplies and AC-DC converters.
For engineers reviewing the TLV2170IDR datasheet, TLV2170IDR pinout, TLV2170IDR application, or TLV2170IDR equivalent, this page delivers verified electrical specs, SOIC-8 package details, dual-channel functional context, and real-world implementation guidance for microvolt-level amplification under wide supply and temperature ranges.
Technical Context
The TLV2170IDR operates from 2.7 V to 36 V (±1.35 V to ±18 V) and maintains rail-to-rail output swing within 350 mV of each rail at full temperature range (–40°C to +125°C). Its input stage accepts common-mode voltages 100 mV below V– and up to 2 V below V+, with phase-reversal protection ensuring stable operation beyond linear input range.
It achieves unity-gain stability driving 200-pF capacitive loads, features 110 dB CMRR and 105 dB PSRR (typ), and delivers 0.4 V/µs slew rate with 20 µs settling time to 0.1% for 10-V steps-enabling use in current-to-voltage conversion and tracking amplifier topologies without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 36-V, low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182IDR | Lower offset (±4 µV), lower noise (5.7 nV/√Hz), higher IQ (550 µA), 10-MHz GBW | Better for precision DC measurements; less suitable for low-power battery operation | Choose OPA2182IDR when sub-µV offset and 10-MHz bandwidth outweigh quiescent current constraints |
| LM2904BDR | Lower cost, wider temp range (–40°C to +125°C), but higher noise (40 nV/√Hz), no EMI hardening, 700-kHz GBW | Suitable for cost-sensitive industrial controls where EMI immunity is not critical | Choose LM2904BDR only when EMI rejection, rail-to-rail output, and microvolt-level drift are not required |
Compared with TLV2170IDR, OPA2182IDR trades 4.4× higher quiescent current for 3.9× lower noise and 8.3× higher bandwidth-ideal for metrology-grade DC accuracy. LM2904BDR offers cost advantage but lacks EMI hardening and rail-to-rail output, limiting use in modern switch-mode power systems.

FAQ
What is the maximum supply voltage rating for TLV2170IDR?
The TLV2170IDR has an absolute maximum supply voltage rating of 40 V across V+ and V– pins. It is fully specified for continuous operation from 2.7 V to 36 V, making it compatible with standard 24-V industrial rails and 36-V battery systems. Operation above 36 V is not recommended for long-term reliability, and transient spikes must remain within the 40-V limit to avoid permanent damage.
Does TLV2170IDR support true rail-to-rail input operation?
The TLV2170IDR supports rail-to-rail *output*, but its input common-mode range extends from (V–) – 0.1 V to (V+) – 2 V under normal operation. Full rail-to-rail input is possible with reduced performance (e.g., increased offset or reduced CMRR). This architecture enables robust operation in single-supply configurations while maintaining precision near the negative rail-critical for current-sense amplifiers tied to ground-referenced shunts.
Can TLV2170IDR drive a 1000-pF capacitive load directly?
No-TLV2170IDR is unity-gain stable up to 200-pF capacitive load. Driving 1000-pF directly causes phase margin degradation, leading to overshoot or oscillation. To interface with heavy capacitive loads (e.g., ADC input filters or long cables), insert a 20–100 Ω isolation resistor between TLV2170IDR's output and the load capacitance. This maintains stability while preserving DC accuracy and bandwidth within system requirements.
What is the typical input bias current of TLV2170IDR at 85°C?
At 85°C, the TLV2170IDR exhibits a typical input bias current of ±100 pA, with a maximum of ±1 nA over the full –40°C to +125°C range. This ultra-low bias current-enabled by precision CMOS input stages-ensures minimal voltage error in high-impedance circuits such as photodiode transimpedance amplifiers or pH probe buffers, where leakage currents would otherwise dominate signal integrity.
Is TLV2170IDR pin-compatible with other dual op amps in SOIC-8 packages?
TLV2170IDR uses a standard SOIC-8 pinout for dual op amps (V–, OUT A, –IN A, +IN A, +IN B, –IN B, OUT B, V+), matching industry conventions. However, it is *not* functionally or electrically pin-compatible with legacy parts like LM2904 or TL072 due to differences in input stage architecture (CMOS vs bipolar/JFET), EMI filtering, and rail-to-rail output capability. Board reuse requires verification of signal routing, decoupling, and layout compatibility with TLV2170IDR's EMI-hardened design.
