Texas Instruments TLV170IDBVR

Overview

TLV170IDBVR from Texas Instruments is a single-channel, 36-V, EMI-hardened operational amplifier in SOT-23-5 package, featuring 1.2 MHz gain bandwidth, 22 nV/√Hz input voltage noise, 125 µA quiescent current, rail-to-rail output, and operation down to 2.7 V supply - used for precision signal conditioning in server power supplies and battery-powered instrumentation.

For engineers reviewing the TLV170IDBVR datasheet, TLV170IDBVR pinout, TLV170IDBVR application, or TLV170IDBVR equivalent, this page delivers verified electrical specs, thermal metrics, real-world use cases, and validated alternative parts - all confirmed against TI's SBOS782A production datasheet (May 2018 revision).

Technical Context

The TLV170IDBVR implements a P-channel input stage with phase-reversal protection, enabling stable operation when inputs extend 100 mV below V− and within 2 V of V+, without output inversion. Its EMI-hardened architecture includes RFI-filtered inputs and 4 kV HBM ESD rating.

It achieves unity-gain stability driving up to 200 pF capacitive load while maintaining 0.4 V/µs slew rate and 20 µs 0.1% settling time (±18 V, 10-V step), making it suitable for current-to-voltage conversion and transducer amplification where low distortion (<0.0002% THD+N at 1 kHz) and microvolt-level signal integrity are critical.

FAQ

What is the maximum supply voltage for TLV170IDBVR?

The absolute maximum supply voltage for TLV170IDBVR is 40 V (V+ to V−), but the recommended operating range is 2.7 V to 36 V. Operation above 36 V risks parametric degradation and reduced long-term reliability, even if within absolute ratings. TI specifies all key parameters - including offset drift, CMRR, and noise - only across the 2.7–36 V range per SBOS782A.

Does TLV170IDBVR support rail-to-rail input?

TLV170IDBVR supports rail-to-rail *output*, but its input common-mode range extends only to (V−) − 0.1 V and (V+) − 2 V under normal operation. Full rail-to-rail input is possible but with reduced performance (e.g., increased offset, lower CMRR). This behavior is explicitly documented in Section 6.7 of the TLV170IDBVR datasheet.

Can TLV170IDBVR drive a 1000-pF capacitive load?

No - TLV170IDBVR is unity-gain stable only up to 200 pF. Driving 1000 pF directly causes peaking and potential oscillation. To interface with heavy capacitive loads, add a 20–50 Ω isolation resistor (ROUT) between OUT and the load, as validated in Figure 14–15 of the SBOS782A datasheet.

What is the typical input bias current of TLV170IDBVR?

The typical input bias current of TLV170IDBVR is ±10 pA at 25°C, rising to ±1 nA over the full –40°C to +125°C range. This ultra-low bias enables high-impedance sensor interfaces (e.g., pH electrodes, photodiodes) without significant input error current, as confirmed in Table 6.7 of the official datasheet.

Is TLV170IDBVR pin-compatible with other SOT-23-5 op amps?

TLV170IDBVR uses standard SOT-23-5 pinout (OUT, V−, +IN, −IN, V+), matching industry conventions - but functional compatibility depends on specifications. For example, while pinout matches LMV321IDBVR, TLV170IDBVR's 36-V rating, EMI hardening, and phase-reversal protection are not replicated in most alternatives, so electrical validation is required per application.
