Product details
Overview
LTC1196-2BCS8#TRPBF from Analog Devices (formerly Linear Technology) is a high-speed, 8-bit successive approximation ADC with differential analog inputs, operating at up to 1.0 MHz sampling rate on 5V supply and 333 kHz on 2.7V supply. It features ±1/2 LSB total unadjusted error over temperature, 3-wire serial I/O, and SO-8 plastic package. It is designed for compact, battery-operated data acquisition systems requiring precise ratiometric or externally referenced conversion.
For engineers reviewing the LTC1196-2BCS8#TRPBF datasheet, LTC1196-2BCS8#TRPBF pinout, LTC1196-2BCS8#TRPBF application, or LTC1196-2BCS8#TRPBF equivalent, key selection criteria include its differential input architecture, auto-shutdown–free operation (vs. LTC1198), 1nA shutdown current capability in compatible variants, and guaranteed 8-bit no-missing-codes performance across 0°C to 70°C.
Technical Context
The LTC1196-2BCS8#TRPBF implements a switched-capacitor SAR architecture with integrated sample-and-hold, supporting full-accuracy input bandwidth up to 1 MHz. Its differential input stage accepts analog signals spanning –0.05 V to VCC + 0.05 V, enabling direct connection to transducer outputs without gain stages.
It uses a 3-wire serial interface (CS, CLK, DOUT) with MSB-first output and fixed 8-bit word length. Conversion timing is synchronized to external clock edges, with tCONV = 600 ns (max 900 ns) at 5V and 1.58 µs (max 2.84 µs) at 2.7V - both specified under full temperature range (0°C to 70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit with no missing codes guaranteed - ensures monotonicity and eliminates code skips in closed-loop control or threshold detection. |
| Sampling Rate (5V) | 1.0 MHz maximum - supports real-time digitization of audio-band and ultrasonic sensor signals without undersampling. |
| Sampling Rate (2.7V) | 333 kHz maximum - enables low-power portable instrumentation while maintaining >7 ENOB at 190 kHz input. |
| Total Unadjusted Error | ±1/2 LSB over 0°C to 70°C - eliminates need for system-level calibration in cost-sensitive industrial monitoring. |
| Supply Current (5V) | 11 mA typical at max sampling - delivers 1 Msps with only 50 mW power, critical for thermally constrained PCB layouts. |
| Input Voltage Range | –0.05 V to VCC + 0.05 V - allows direct interfacing to ±100 mV bridge sensors or op-amp outputs without level-shifting. |
| Reference Input | Dedicated VREF pin - supports independent reference sourcing (e.g., precision bandgap) for ratiometric immunity to supply drift. |
Pinout & Package
Package: 8-lead plastic SO (SO-8), 150°C max junction temperature, θJA = 175°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS (Pin 1) | Chip Select Input | Active-low enable: drives internal logic and initiates conversion sequence; high state places device in standby (leakage only). |
| +IN (Pin 2) | Differential Analog Input (+) | High-impedance input (30 pF) accepting signal referenced to –IN; supports common-mode voltage up to VCC. |
| –IN (Pin 3) | Differential Analog Input (–) | Matches +IN characteristics; defines differential span; rejects common-mode noise when used with matched source impedances. |
| GND (Pin 4) | Analog Ground | Must connect directly to low-impedance analog ground plane - separates noise-sensitive analog paths from digital return currents. |
| VREF (Pin 5) | External Reference Input | Defines full-scale range independently of VCC; accepts 1 V to 5 V; enables precision measurement with stable external references. |
| DOUT (Pin 6) | Serial Data Output | CMOS-compatible, MSB-first output; data valid 55 ns after CLK↑ (5V); tri-states when CS is high. |
| CLK (Pin 7) | Serial Clock Input | Accepts 0.01–14.4 MHz (5V) or 0.01–5.4 MHz (2.7V); rising edge clocks data out and controls sampling timing. |
| VCC (Pin 8) | Power Supply | Operates from 2.7 V to 6 V; requires local 1 µF ceramic bypass to GND; powers internal bias, reference buffer, and logic. |
Key Features
| Feature | Design Value |
|---|---|
| Differential analog input | Enables rejection of common-mode noise from transducers, motors, or long cables - critical for EMI-prone industrial environments. |
| Independent VREF pin | Decouples accuracy from VCC variation - supports ratiometric sensing with resistive bridges or RTDs without additional regulators. |
| 8-bit no-missing-codes guarantee | Ensures deterministic behavior in safety-critical applications like overvoltage trip detection or motor commutation feedback. |
| Low 50 mW power at 1 Msps | Reduces thermal load in dense mixed-signal boards - avoids derating or forced-air cooling in compact enclosures. |
| SO-8 footprint compatibility | Enables drop-in replacement for legacy 8-bit ADCs (e.g., MAX111x, AD78xx) without PCB redesign or layout revalidation. |
Applications
| Portable Instrumentation | Disk Drive Read Channel |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1113EKA+T | Single-ended input only; no dedicated VREF pin; 2.7–5.25 V supply; 1.2 Msps max; ±1 LSB INL. | Requires external gain/level-shift for differential sensors; less suitable for ratiometric bridge measurements. | Select when cost is primary constraint and differential input not required; verify layout for higher noise sensitivity. |
| AD7810BRZ-REEL7 | Single-ended input; SPI-compatible 4-wire interface; 1.25 Msps; ±0.5 LSB INL; 2.7–5.25 V; no auto-shutdown. | Lacks differential capability and independent reference - limits use in precision transducer interfaces. | Prefer for systems already using SPI peripherals; avoid where common-mode rejection or external VREF is needed. |
Compared with MAX1113EKA+T and AD7810BRZ-REEL7, the LTC1196-2BCS8#TRPBF uniquely delivers guaranteed differential input, dedicated VREF, and ±1/2 LSB TUE over temperature - making it the only option among the three qualified for uncalibrated, high-noise industrial sensor front-ends.

FAQ
What is the maximum sampling rate of the LTC1196-2BCS8#TRPBF at 5V supply?
The LTC1196-2BCS8#TRPBF achieves a maximum sampling rate of 1.0 MHz when operated at VCC = 5V and fCLK = 12 MHz, as confirmed in the AC Characteristics table (page 4) of the official datasheet. This rate is guaranteed across the full 0°C to 70°C operating temperature range for the -2B grade.
Does the LTC1196-2BCS8#TRPBF support true differential input operation?
Yes, the LTC1196-2BCS8#TRPBF supports true differential input operation between pins +IN (Pin 2) and –IN (Pin 3). Its input structure allows measurement of signals floating on DC common-mode voltages up to VCC, with full-scale range defined by VREF - a capability explicitly documented in the Applications Information section (page 14).
What is the total unadjusted error specification for the LTC1196-2BCS8#TRPBF over temperature?
The LTC1196-2BCS8#TRPBF has a total unadjusted error (TUE) of ±1/2 LSB maximum over the full operating temperature range of 0°C to 70°C, as stated in the Converter and Multiplexer Characteristics table (page 3) for LTC1196-1B/LTC1196-2B grades. This includes offset, full-scale, linearity, and hold-step errors.
Can the LTC1196-2BCS8#TRPBF operate from a 3V supply?
Yes, the LTC1196-2BCS8#TRPBF is fully specified for operation from 2.7 V to 6 V. At VCC = 2.7 V and VREF = 2.5 V, it delivers up to 333 kHz maximum sampling rate and consumes only 2.0 mA typical supply current - verified in the Recommended Operating Conditions table (page 5) and Supply Current vs Sample Rate graph (page 7, G03).
Is there a pin-compatible alternative to the LTC1196-2BCS8#TRPBF with auto-shutdown?
No - the LTC1196-2BCS8#TRPBF does not include auto-shutdown functionality. That feature belongs exclusively to the LTC1198 family (e.g., LTC1198-2BCS8#TRPBF), which uses a different pinout (DIN instead of VREF) and multiplexer architecture. The two families share the SO-8 package but are not pin-compatible due to differing Pin 5 and Pin 8 functions.
