Texas Instruments TLV2342IDR

Overview

TLV2342IDR from Texas Instruments is a dual-channel, low-voltage, high-speed operational amplifier in the LinCMOS™ family, designed for single-supply operation from 2 V to 8 V over –40°C to 85°C. It delivers 2.1 V/µs slew rate and 790-kHz unity-gain bandwidth at 3 V, features rail-to-rail output swing (including negative rail), common-mode input range extending to V_DD – 1 V, and ultra-high input impedance (10¹² Ω typical). It is used in portable sensor signal conditioning and battery-powered audio preamplifiers.

For engineers reviewing the TLV2342IDR datasheet, TLV2342IDR pinout, TLV2342IDR application, or TLV2342IDR equivalent, key selection criteria include its 2.1 V/µs slew rate at 3 V, 790-kHz bandwidth, rail-to-rail output capability, input voltage range extending below ground, and low 0.65 mA supply current - all validated across –40°C to 85°C with full characterization at both 3 V and 5 V.

Technical Context

The TLV2342IDR employs Texas Instruments' silicon-gate LinCMOS™ process to achieve ultra-low input bias current (0.6 pA typical at 25°C) and high input impedance while maintaining ac performance approaching BiFET op-amps. Its architecture supports true single-supply operation with input common-mode range from V_SS to V_DD – 1 V and output swing to within 120 mV of the negative rail and 1.75 V of the positive rail at 3 V.

Internal ESD protection meets MIL-PRF-38535 Method 3015.2 (2000 V HBM), and latch-up immunity is designed-in. The device operates down to 2 V supply and sustains ±30 mA output current without damage, with unlimited short-circuit duration at T_A ≤ 25°C when dissipation limits are observed.

Key Specifications

Pinout & Package

TLV2342IDR is housed in an 8-pin SOIC (D package), tape-and-reel format (R suffix), with 1.27 mm pitch and JEDEC MS-012AC outline. Pin 1 is marked by a beveled corner or dot.

FAQ

What is the minimum supply voltage for reliable operation of the TLV2342IDR?

The TLV2342IDR operates reliably down to 2 V supply voltage across its full specified temperature range of –40°C to 85°C. It is fully characterized and tested at both 3 V and 5 V, with all key parameters - including slew rate, bandwidth, and input offset - guaranteed at 2 V minimum. This makes TLV2342IDR suitable for direct connection to single-cell lithium or alkaline batteries without regulation.

Does the TLV2342IDR support rail-to-rail input operation?

The TLV2342IDR supports rail-to-rail *output* operation but not rail-to-rail *input*. Its common-mode input voltage range extends from the negative supply rail (V_SS) up to V_DD – 1 V at 25°C. This means it accepts inputs at ground (V_SS) and up to 1 V below the positive rail - sufficient for most single-supply sensor interfaces but not full rail-to-rail input swing. TLV2342IDR does not violate this specification under normal operating conditions.

What is the typical input bias current of the TLV2342IDR at 85°C?

At 85°C, the TLV2342IDR exhibits a typical input bias current of 175 pA, with a maximum of 2000 pA across the full temperature range (–40°C to 85°C). This value is confirmed in the "TLV2342I electrical characteristics" table under IIB test conditions (VO = 1 V, VIC = 1 V). The increase from 0.6 pA at 25°C reflects predictable thermal behavior of the LinCMOS™ process, and TLV2342IDR remains suitable for high-impedance sensor applications even at elevated temperatures.

Can the TLV2342IDR drive a 10 kΩ load while maintaining rail-to-rail output swing?

Yes, the TLV2342IDR maintains rail-to-rail output swing into a 10 kΩ load. At 3 V supply and 25°C, its high-level output voltage (VOH) is 1.75 V (min) with –1 mA load, and low-level output voltage (VOL) is 120 mV (max) with +1 mA load - confirming swing to within 120 mV of V_SS and 1.25 V below V_DD. These values are explicitly specified in the "TLV2342I electrical characteristics" table and apply to TLV2342IDR under standard operating conditions.

Is the TLV2342IDR pin-compatible with other devices in the TLV234x family?

Yes, the TLV2342IDR is pin-compatible with all 8-pin D-package variants in the TLV234x family, including TLV2342ID, TLV2342IP, and TLV2342IPWLE. All share identical pinout: OUT1, IN–1, IN+1, V_SS, V_DD, OUT2, IN–2, IN+2. The "R" suffix denotes tape-and-reel packaging only - no functional or pinout difference exists between TLV2342ID and TLV2342IDR. This allows drop-in replacement during manufacturing without PCB changes.
